Prime Day is an avalanche of deals, but frankly most of these so-called hot buys aren’t such great deals at all, or else are discounts on products you shouldn’t buy at any price. We’ve filtered through thousands of deals to find the sales that really matter, but ultimately, it’s our readers who determine what’s most compelling. These are the things our readers are buying the most this Prime Day.
1. Free money at Amazon
This one’s pretty simple: Amazon is giving you an extra $10 in store credit if you buy at least $40 worth of Amazon gift cards. Yep, that’s free money, provided you’re interested in shopping at Amazon to begin with. You can input a custom amount of exactly $40, or go higher if you want. Just remember to use the code GC20PRIME to get the credit.
2. A safe place for all of your bulk groceries
Rubbermaid Brilliance Storage 24-Piece Plastic Lids
Deal price: $28; street price: $40
Tired of eating stale cereal and finding grains of rice all over the inside of your kitchen cabinets? You need some good dry food storage containers, and these supremely well-designed jars from Rubbermaid are the best of the best. Their lids seal tightly, they stand up to repeated cleaning in the dishwasher, and their rectangular shape helps them save space in your pantry (they stack on top of each other neatly, too). This 24-piece set comes with sizes ranging from ½ cup to 7 cups, so you can keep everything from coffee to bulk flour fresher longer.

3. Never leave the garage open again
If you’re like me, you’ve probably been chewed out by your significant other for driving off and leaving your garage door open. (I swear I hit the button!) A smart garage-door controller takes the guesswork (and the frantic U-turn) out of those “Did I leave the garage door open?” moments by letting you check the door status and even close or open it from your phone, no matter where you are. Chamberlain’s MyQ controller is a great choice if you have a compatible Chamberlain, LiftMaster, or Craftsman opener, and it works with popular smart-home systems like Xfinity, Alarm.com, and HomeKit (via an add-on bridge device).

4. The best way to prank your kids
Yes, I know, Amazon’s Alexa-powered smart devices are good for all kinds of things—tracking packages, getting the forecast, playing music, and more—not just driving your progeny crazy. But my colleague Jon Chase’s ode to messing with his kids via Alexa integrations is so good, I just wanted to call it out again here. The Echo Dot is Amazon’s cheapest Alexa speaker, and it works great anywhere you don’t need room-filling audio quality: at your bedside, on your office desk, or in the garage. At this price, why not put ’em in every room?

5. A library in the palm of your hand
I’ve been hanging on to my battered 3rd-generation Kindle Paperwhite for years—toting it across five countries and four states and reading hundreds of books in the process—but this deal might be the one that gets me to finally upgrade. The 10th-generation model (our pick for the best ebook reader) has a beautifully bright and evenly lit display, Bluetooth connectivity, and waterproofing. You can even tack on three months of Kindle Unlimited for free in an introductory offer, so you’ll have books ready to go as soon as it’s in your hand.

6. For your best smile
Crest 3D White Professional Effects Whitestrips Kit
Deal price: $28; street price: $45
Teeth whitening is pretty simple tech: Our research shows that all you need to get those pearly whites is hydrogen peroxide bleach and time. These popular strips certainly provide the bleach, and as long as you’re cool with applying them every day for a couple of weeks, the science shows that they work. With these strips at nearly half their usual price, this is the best time to try them out if you’ve been meaning to brighten up your smile.

7. Brave the elements
I live in the high desert, where it almost never rains, so I don’t even own an umbrella. But if I lived a few hours away, across the Cascade Mountains in Portland, Oregon, you can bet I’d be eyeing this deal. This umbrella is our top pick thanks to its sturdy nine-rib construction, wide canopy, and easy-to-grip handle, as well as the fact that it comes in a wide variety of colors. Despite its surprisingly low price, this umbrella also comes with a lifetime refund-or-replacement guarantee.

8. Cleaner floors with almost no effort
A good robot vacuum won’t replace your regular vacuum cleaner, but it should keep your standard vacuum in the closet for a lot longer between uses. A variant on our current top pick, the Roomba 692 is a reliable cleaner that’ll keep your floors tidy on a daily basis with almost no effort on your part. It’s Wi-Fi connected, and it also works with Google Assistant and Alexa, so you can yell at it to clean up your messes. (Okay, you can yell at any robot vacuum, but this one will actually respond.)

9. Finally sleep through the night
My partner is a notoriously light sleeper, disturbed by airflow, the sound of our dog breathing, and ambient light. Last year, after we moved into our new place, which has huge, floor-to-ceiling windows in the master bedroom, she was a total mess. But wearing this mask—and banishing the dog to the hallway—gave her some surprisingly cost-effective relief. Already a bargain at its usual asking price of $12, this comfortable eye mask is an absolute steal at 25% off, especially if it saves you from dealing with a sleep-deprived housemate.
10. Smarter than your smart TV
If you bought a TV in the past few years, it probably came with “smart” software that could stream TV and movies. But unless you bought a Roku-enabled TV, it’s probably not nearly as smart as the Roku Streaming Stick+. Our favorite option for high-quality streaming, this tiny device plugs into an open HDMI port, gets power from a TV USB port, and provides access to popular platforms like Netflix, Hulu, Amazon Prime, Disney+, Apple TV+, HBO Max, and Plex. Roku’s interface is easy to navigate, has a convenient voice-search function that prioritizes free content, and even lets you listen to shows and movies via headphones (through the Roku app on your phone) so you don’t wake up your family or roommates. And despite its small size, the Streaming Stick+ has enough processing power to handle 4K footage, including HDR10 content.

11. Be your own barber
Philips Norelco Multigroom Series 7000 MG7750 Beard Trimmer
Deal price: $45; street price: $55
Different people have different comfort levels when it comes to stepping outside during the pandemic. Personally, I don’t go anywhere I don’t have to go, and that includes going to visit my barber. (Sorry, Jake.) To keep from looking like a mountain man, I picked up this trimmer kit. It does indeed take awesome care of my beard, but I’ve also used it to give myself what I can honestly describe as a pretty decent-looking fade. Those 14 guide combs really come in handy!

12. Keep tabs on your temps
Speaking of pandemic things, here’s a great deal on a reliable thermometer. In our testing, we found that this stick thermometer returned accurate, consistent results within 10 seconds—quicker than most of the competition. It’s longer and more flexible than other stick thermometers, too, so you can read it while it’s taking your temp. This is something every family should have in the medicine cabinet, and it’s rarely been cheaper.

13. You can never have enough razors
Gillette Mach3 Sensitive Men's Razor Blades, 20 Blade Refills
Deal price: $28; street price: $48
If you shave, but you aren’t the beardy type and haven’t been seduced by the cult of Harry’s and Dollar Shave Club—or gone all-in on straight razors and artisan shaving lotion—there’s a good chance you’re shaving with a Gillette Mach3. And if that’s the case, you know how expensive blade refills can be. Here’s a great discount on a 20-pack, enough to keep you going for a while before your next re-up. We love these blades because they provide a reliably great shave without too much irritation, and they don’t get clogged with hair.

14. Amazon Music Unlimited
Hi there, longtime Spotify user. Amazon would like to tempt you away from your music streaming service of choice, so it’s offering you, as a new subscriber, four months for one whole dollar. Yes, that’s basically free. And it’s a pretty attractive service, as well. Amazon’s music library (around 50 million songs) is comparable in size to Spotify’s, and if you have Alexa devices, you can make more complex requests for moods, themes, and activities than you can with Spotify.
15. Nothing says fall quite like lip balm
I don’t wear lip balm—it’s a texture thing—but I buy a lot of it for my partner, and even I know that Burt’s Bees is a stone-cold classic. It may not have wild mixologist-inspired flavors or protect your lips from sunburn, but it’s thick and waxy (thanks, bees), and it keeps those smackers hydrated all day long with little reapplication necessary. Our testers reported that the original peppermint flavor on sale here produced a nice tingling sensation, though people with sensitive lips may need to look for another (sadly non-sale, but still affordable) flavor.
