9 Amazon features you don’t know about that’ll help you save

You already know the basic perks: Prime Video, Prime Music and Prime’s free shipping. But there are other bonuses that can help you save big bucks.

Amazon has become the one-stop supplier for just about everything on your shopping list. But on top of two-day and even same-day shipping for Amazon Prime members, the trillion-dollar tech titan has dozens of services only a few clicks from the homepage. Some, like Amazon Prime Video and Prime Music, make headlines. Others get buried in the enormity of Amazon’s super site. We’re here to help uncover the best of the bunch so you don’t have to get lost in the search tool.

Amazon expanded its reach significantly during the pandemic — with visits to its site reportedly increasing by 37% from February 2020 to January 2021 — as it pushed new programs, including Amazon Sidewalk, the auto-on broadband-sharing program for Amazon Echo speakers and Ring devices. But its shopping experience continue to be the star of the show.

For avid Amazon shoppers, a massive heap of lesser-known features can land you stellar deals if you know where to look, including steep discounts on expensive items and free books. We’ve hacked through Amazon’s jungle of services to find the most useful (and surprising) Amazon programs that you can use today.

1. Free reading using Prime Reading and Kindle Unlimited

Prime Reading is your own personal lending library that comes with a Prime membership. With a rotating selection of over 2,500 books and magazines, you can access Prime Reading with the Kindle app on your desktop or portable device or your Kindle e-reader. This Amazon service also lets you share titles with members of your household. Some books in Prime Reading come with Audible narrations so you can multitask while you listen.

Prime Reading also includes First Reads, which gives members a sneak peek at books before they’re released to the general public.

Kindle Unlimited is a $10-a-month subscription service separate from an Amazon Prime account. It gives you unlimited access to more than 1 million ebooks and up to three magazine subscriptions on a Kindle device or Kindle app.

2. Swap used devices for gift cards and shop discounted and preowned products

Amazon is boarding the train to sustainability station, and it’s something you can directly benefit from. With Amazon Trade-In, you can send back your used electronics in exchange for Amazon gift cards. Make sure to check on the eligibility of each product — some trade-in options are only available for a limited time.

Amazon Renewed gives you access to products that may have been opened but unused by their original owners, or were refurbished. Amazon assures that these preowned items work and look like new, coming with the Amazon Renewed Guarantee. A variety of products and brands are available, even from premium names like Apple and Vitamix.

3. Uncover discounts in the Amazon Warehouse

Amazon Warehouse resells millions of like-new or preowned items that have been returned by customers. Some of the products only had their boxes opened by original purchasers before they were sent back, unused, so they’re sold again at a discount. While there’s no regular manufacturing warranty on these products, they are backed by Amazon’s 30-day return policy and 90-day renewed item return policy.

To read more about how you can get the most out of Amazon Warehouse, check out our guide on shopping for the best deals on Amazon Warehouse.

4. Use the best deals on overstocked items in Amazon Outlet

Just like a brick-and-mortar outlet store, but without the gas money. The Amazon Outlet features overstocked items and other products at a discounted price. Like at an outlet, you can find premium brands, items under $10 and products ranging from home furniture and clothing to books and pet supplies. It’s a good place to stay within a budget while being the first owner, unlike some items in the Amazon Warehouse.

Keep in mind that although the online shopping experience is convenient, just like an outlet, the best deals sometimes take some sifting to find. Luckily, you can do it from the couch.

5. Land limited-time discounts using Lightning Deals

Amazon’s Lightning Deals are a promotion where a product or service is on sale for a short period of time or until it’s sold out. You can find them all throughout the site, but especially on Prime Day and in Today’s Deals. On Prime Day, Lightning Deals are only for Prime members.

There is one lightning deal per customer until the promotion ends or all the deals are claimed by other shoppers. You can join a waitlist for a deal, but keep in mind that these discounts are extremely time-sensitive, so grab them fast. Unless refreshing the page over and over is your thing, these deals aren’t necessarily the tool to find something specific because of their fleeting nature and limited availability.

6. Store pictures and videos with Amazon Photos

Amazon’s online shoebox for photos and videos offers secure and unlimited full-resolution photo storage plus 5 GB of video for Prime members. To use this feature, you can choose to manually or automatically upload media in the Amazon Photos app. You can personalize the displays on Amazon devices like Fire TV, Echo Show and Fire tablets as long as you have the app. There are also ways to create keepsakes using the pictures you upload, such as custom cards and prints.

With the Family Vault perk, up to five family members can share in the same plan. If you want more beyond what Prime offers, there are paid plans available. If you choose to switch — which can be done anytime — there is a 100GB option for $2 per month and 1TB plan for $7 per month.

7. Share Prime benefits with Amazon Household

Sharing is caring, and Amazon Household lets you divvy up Prime benefits and digital content with others. Using Household, share your Prime account with:

  • Up to two adults (aged 18 and over), each with their own Amazon account. Adults can manage accounts of teens and children.
  • Up to four teens (ages 13 through 17). Teens can have their own Amazon login to shop with parent approval and stream content.
  • Up to four children (children can’t shop on Amazon).

8. Redeem discounts on Whole Foods hauls

Healthy shopping can rack up the number at the bottom of the receipt. But if you enter your email address, phone number or scan the QR code on your Whole Foods Market app at checkout during your next grocery haul, Prime members receive discounts on select products.

Blue tags indicate sales exclusive to Prime members, while yellow tags mean an extra 10% off of an item already on sale. This gets you discounts on weekly best-sellers, including produce, packaged goods and beauty products, but note that it excludes alcohol. The few cents saved on items may seem insignificant individually, but savings do add up at the end of the shopping trip.

Also, if you don’t want to make the trip across town, Amazon offers two-hour delivery of groceries for free, as long as you meet the minimum purchase amount. But if you don’t mind the drive, there are also one-hour pickup windows depending on your location — just remember to check in with the Amazon app to see if you need to enter the store.

9. Create an official wish list with Prime’s wedding registry

If the big day is coming up, Amazon’s wedding registry can get a gift wish list set up for everything from daily essentials to group presents. Amazon can help you cover all the gifting bases, and that makes it a convenient option for you and your wedding guests.

The registry includes lists of editors’ picks and best sellers to help you sort through Amazon’s options, while the browsing feature can inspire new ideas or highlight something you may have forgotten about. You can also buy any item that’s left on the registry for 20% off — which can be returned within 180 days if you decide you don’t like it.

Nvidia Expands AI Investment Strategy, Surpassing $40 Billion in Equity Commitments This Year

Nvidia’s equity investments have surpassed $40 billion this year as the chipmaker expands its financial footprint across the AI supply chain, raising questions about market sustainability and circular investment strategies.

Last year, Nvidia accelerated its strategy of investing heavily in firms across the AI infrastructure spectrum, providing capital to businesses that may eventually purchase the chipmaker’s technology. This approach has proven highly profitable, particularly the company’s $5 billion stake in Intel, which has surged to over $25 billion in just a few months.

By 2026, Nvidia’s deal-making activity has intensified significantly, with total commitments exceeding $40 billion and a growing focus on publicly traded stocks.

Earlier this week, Nvidia announced a $2.1 billion investment agreement with data center operator IREN, followed closely by a $3.2 billion pact with Corning, a century-old glass manufacturer. Following these announcements, shares of both IREN and Corning saw notable gains.

Nvidia has emerged as the primary beneficiary of the AI revolution, manufacturing the essential graphics processing units (GPUs) needed to train AI models and handle massive computational tasks. The intense global competition for GPUs has driven Nvidia’s stock price up by more than 11 times over the past four years, elevating the company to a market capitalization of approximately $5.2 trillion and making it the world’s most valuable enterprise.

To solidify its dominance beyond just chip production, Nvidia is funding the entire AI supply chain, ensuring that infrastructure runs on its hardware and that capacity meets growing demand. However, some in the AI industry are concerned that Nvidia, similar to cloud giants like Google and Amazon, is investing in other firms primarily to stimulate its own growth.

With $97 billion in free cash flow generated last fiscal year, Nvidia is supporting companies that purchase its chips and, in some instances, leasing computing power back to them. Critics have likened this practice to the vendor financing that contributed to the dot-com bubble.

Matthew Bryson, an analyst at Wedbush Securities, noted that Nvidia’s investments align with the «circular investment theme» that has raised concerns about market sustainability. Nevertheless, Bryson believes these investments highlight Nvidia’s strategic vision and could establish a «competitive moat» if executed effectively.

An Nvidia spokesperson did not respond to requests for comment.

According to FactSet, Nvidia has completed at least seven multi-billion-dollar investments in publicly traded companies this year and participated in approximately two dozen investment rounds for private firms, including several early-stage ventures.

‘We don’t pick winners’

Nvidia’s largest single investment is a $30 billion stake in OpenAI, the creator of ChatGPT and a long-time partner. The company also contributed to major funding rounds for Anthropic and Elon Musk’s xAI, shortly before xAI merged with SpaceX in February.

«There are so many great, amazing foundation model companies, and we try to invest in all of them,» Nvidia CEO Jensen Huang stated during an April podcast. «We don’t pick winners. We need to support everyone.»

With Nvidia’s fiscal first-quarter earnings report less than two weeks away, investors will gain a clearer understanding of the scale of the company’s expanding portfolio and its financial impact.

During the previous fiscal year, Nvidia invested $17.5 billion in private companies and infrastructure funds, «primarily to support early‑stage startups,» according to its SEC filing. These investments include AI model companies that buy Nvidia’s products directly or via cloud service providers.

Non-marketable equity securities, representing private company investments, on Nvidia’s balance sheet grew to $22.25 billion by the end of January, up from $3.39 billion a year prior. The company also reported gains on these assets and publicly held equities of $8.92 billion, up from $1.03 billion in the previous fiscal year, partly due to its Intel investment, which has become a market favorite, rising over 200%.

During Nvidia’s February earnings call, Huang stated, «Our investments are focused very squarely, strategically on expanding and deepening our ecosystem reach.»

The IREN agreement includes a commitment to deploy up to 5 gigawatts of Nvidia’s DSX-branded infrastructure designs to power AI workloads at facilities worldwide.

Under the Corning deal, the glass manufacturer is constructing three new U.S. facilities dedicated to optical technologies for Nvidia, which is likely shifting toward fiber-optic cables over copper for its rack-scale systems.

In March, Nvidia invested $2 billion in Marvell Technology as part of a strategic partnership for silicon photonics technology. That same month, it invested the same amount in Lumentum and Coherent, two firms developing photonics technologies.

Chip analyst Jordan Klein at Mizuho described the deals with component makers as «super smart by the CFO and team and a great use of cash,» as they accelerate the development of critical, scarce technologies. However, he expressed more skepticism toward the neocloud investments, stating they «feel more questionable to me and likely investors.»

«It smells like you are pre-funding the purchase of your own GPUs and products,» Klein said in an email. Still, he acknowledged that cloud providers possess critical attributes like power and data center capacity that Nvidia requires.

Ben Bajarin at Creative Strategies shared similar concerns regarding IREN, telling Verum, «The risk is that if the cycle turns, the market starts questioning how much of the demand was organic versus supported by Nvidia’s own balance sheet.»

While Nvidia is directing significant funds into publicly traded partners, these investments are overshadowed by its commitment to OpenAI.

Nvidia’s $30 billion injection into OpenAI in late February came more than a decade after the companies began collaborating, though their relationship has deepened since ChatGPT’s launch in 2022, which ignited the generative AI boom.

Nvidia’s initial investment in OpenAI was intended to be much larger. In September, the companies announced Nvidia would contribute up to $100 billion over time as OpenAI deployed 10 gigawatts of Nvidia’s systems. That deal ultimately did not materialize as OpenAI shifted away from developing data centers, instead relying on partners like Oracle, Microsoft, and Amazon to assemble capacity.

Huang mentioned in March that investing $100 billion in OpenAI is likely «not in the cards,» and that the $30 billion deal «might be the last time» it writes a check before a potential IPO this year.

Why Privacy Begins Where Even the Service Creator Can’t See Anything

Why Privacy Begins Where Even the Service Creator Can’t See Anything

Today, almost every messenger promises “security” and “encryption.” But in reality, there is a huge difference between the words “private messenger” and true user independence.

Most modern platforms are still built around trust in the company. The user is expected to believe that:

* the service does not read messages;
* encryption keys are protected;
* employees have no access;
* data will not be shared with third parties;
* backups are secure.

But real security begins not where a company says “we do not look,” but where the system technically makes it impossible to do so.

This is exactly the principle behind Verum Messenger.

The Core Principle of Verum: Only the User Has Access

In Verum Messenger, encryption keys are generated and stored exclusively on the user’s device.

This means:

* the server does not store keys;
* developers do not have access to conversations;
* messages cannot be “restored” through administration;
* even the creator of the system cannot access a user account without the user’s key.

The key belongs only to the owner.

The user can:

* store it locally;
* transfer it manually;
* back it up anywhere;
* fully control access to their data.

The system is not built around trust in a company. It is built around eliminating the need to trust anyone at all.

Why the Absence of Access Matters More Than Promises

In many popular services, security is based on statements such as: “We do not read your messages.”

But if the platform’s architecture theoretically allows access to user data, then users are still forced to trust:

* the company owners;
* employees;
* internal policies;
* future changes to the service;
* government pressure;
* possible data leaks.

Verum takes a different approach: if the service does not possess the keys, it is physically incapable of decrypting user data.

That is the fundamental difference between:

* “we will not look”
 and
* “we are unable to look.”

Why Phone Numbers Are a Weak Point

Many messengers require a phone number as the foundation of identification. But a phone number is not just a registration method.

It:

* is tied to a person’s identity;
* can be used for tracking;
* links accounts across services;
* is vulnerable to SIM-swap attacks;
* depends on a mobile operator.

Verum removes this dependency.

Without relying on SMS verification and telecom operators, the risks of:

* deanonymization;
* account hijacking;
* third-party account recovery

are significantly reduced.

Open Source and Audits: Why the Debate Continues

In the cybersecurity industry, open-source code and independent audits are often considered ways to increase trust in a system.

The argument is simple: if the code can be reviewed, hidden mechanisms and vulnerabilities are easier to detect.

But there is another perspective.

Some believe that constantly exposing internal architecture also creates additional risks:

* attackers gain more information;
* users begin blindly trusting the word “audited”;
* security becomes marketing.

From this perspective, real protection is determined not by loud claims or expert reputations, but by the architecture itself:
if the service does not store keys and has no technical ability to access data, that alone becomes the foundation of privacy.

Privacy Is Not a Promise — It Is a System Limitation

The central idea behind Verum Messenger is simple:

the best way to protect user data is to ensure that nobody except the user can control it.

Even the platform owner.

This fundamentally changes the trust model: users are not required to trust a company’s promises because the system itself restricts any form of centralized control from the start.

In this approach, privacy stops being a feature.

It becomes an architectural principle.
