The best Prime Day deals under $50: Save up to 60% on these wallet-friendly finds

If your less-than-glowing chompers could use some restoration, the folks at Crest say these bestselling strips can make teeth up to 20 shades whiter in just 22 days (that's almost one shade per day!). 

According to the brand, you're guaranteed to have a noticeably whiter smile, and with this kit, you'll get some bonus express treatments for same-day results. This Prime Day sale drops the price to as low as we've seen it in years. Now that's something to say "cheese!" about.

This cool gadget is more than just an alarm clock — though it's a super-sleek one, at that. In addition to the time, it'll tell you the weather, play music and even control compatible smart devices. 

At close to 45% off, this is the lowest price we've ever seen for this brand-new smart speaker. Check out our tech editor's review for more. 

These No. 1 bestselling pillows are hits among hundreds of thousands of Amazon shoppers (really) and Yahoo readers can't stop scooping them up, either. They're made of a cooling gel to help keep those uncomfortable night sweats at bay, and the plush Oeko-Tex Standard certified material will feel like heaven while you sleep. 

They're not often on sale for less than they are now (40% off). Check out our full Beckham Hotel Collection Bed Pillows review for more.

Keep those pearly whites, well, pearly and white with this No. 1 bestselling electric toothbrush. It provides 40,000 vibrations per minute to kick plaque to the curb, and you'll get eight brush heads included — enough to last 2½ years!

At 50% off, our price trackers tell us this is just about as low as it gets. Be sure to check out our roundup of the best electric toothbrushes — where it was named "best overall toothbrush — for more. 

Yard in need of some heavy-duty pruning? This small but mighty chainsaw is powerful enough to take down tree branches, yet weighs under 2.5 pounds. Plus, this top-seller is cordless for even more convenience, and at over 60% off, this is one of the best prices we've seen it marked down to.

One Yahoo editor gave it a try, writing, "While testing the Saker, I first noticed that it was very easy to hold in one hand. I also appreciated the safety features, including a safety lock that must be pressed before the saw activates. This gave me some comfort that it wouldn't just 'go off' if I squeezed it too tight while walking between locations. It's also easier to use than something like pruning shears, which can be heavy and unwieldy and take much longer to get the same job done."

Rise and grind! Just kidding — with this top-selling Keurig, making coffee is as simple as filling the tank with water, popping in a K-Cup of your choice and pressing a button. 

Let's face it, mornings can be hectic, and the last thing you need as you're rushing around is an involved java-making process. This quick brewer takes all the work out, and it's back down to its Black Friday price ($49.99 — made the cut by a cent!).

This versatile skillet ain't no flash in the pan — it's been a staple in one Yahoo Life editor's kitchen for years. Among its many perks are its lightweight, 2-pound design, as well as the removable silicone grip on its handle, which will protect your hands while you cook. 

It's also dishwasher-safe, but our editor says, "Cleanup is a breeze and only requires a few swipes with a soapy sponge, even around the rivets that secure the handle." It's currently within $2 of the lowest price we've seen all year.

Alright, car crumbs — you've met your match with this wildly popular handvac, on sale for nearly 40% off with Yahoo's exclusive code 15WorxPBDD15. Destroy all evidence of those Mickey D's remnants, thanks to its three detailing attachments and handy LED light. 

It's also got a 16-foot cord for reaching the trunk, and at a mere 2.6 pounds, you won't have to put your arms through a workout while you use it.

Thousands of Amazon shoppers love these sturdy containers, which have airtight seals to keep food fresh. They're made of glass — but not just any glass. We're talking about borosilicate glass, which is used on thermal tiles in space shuttles. Not only does it conveniently allow you to see what's packed inside, but it's oven-safe up to 1,040°F and can go in the microwave without a lid. You can also store these containers in the freezer if you have leftovers you know you won't get to right away.

Now, some real talk: We've never seen this set listed for the $70 original price, but while that might be inflated, you're still getting a great deal considering how many pieces are in this collection. 

Never again juggle a brush in one hand and a bulky hairdryer in the other. This 2-in-1 appliance dries and straightens at the same time for sleeker, smoother tresses — no visit to the salon necessary. 

If you're not ready to splurge on the Dyson Airwrap, this is a great bet. And while the $134 original price looks to be exaggerated, the on-sale price of $32 makes this a highly worthwhile deal. 

These days, it's hard to find a single decent knife for less than 50 bucks, let alone an entire collection! What sets these knives apart is that they're made of a single piece of high-carbon stainless steel, which makes them a breeze to clean. 

The attractive wooden block they're stored in also has a fun surprise — a built-in sharpener to keep the blades nicely honed. The most we've really seen this set listed for is around $80, not $130, but at $48, we've never seen it for less than it is now. 

If you're on the hunt for an anti-hair-thinning solution, this duo was specially formulated with that in mind. Both the shampoo and conditioner in this set contain biotin, an ingredient that can help increase hair's strength by delivering essential moisture to prevent breakage for a more voluminous look. 

The price of this pair has only dipped this low one other time this year, FYI!

Shoppers say this flowy fall essential "looks like a high-end cashmere," but it costs a fraction of the price. The elegant turtleneck design gives it an even more expensive appearance and will keep things nice and toasty on chillier days; plus, you can't go wrong with that 50% discount. 

Come winter, it'll make the most stylish layering piece — at this price, stock up on a few colors!

There's no need to spend an hour on your knees furiously scrubbing away at your shower when you have one of these electric doodads on hand. This one has thousands of great reviews and two adjustable speeds to cut through bathtub grime, soap scum and grout stains with little to no elbow grease on your part. 

Its retractable handle allows you to clean without crouching over, and it comes with four different brushes for tackling a variety of spaces in your home. This is close to as low as it gets, folks!
