Scoop up a popular Ninja personal blender for $39 — 35% off! — plus 9 more deals

It's no secret — workout clothes can be expensive. (which, if you think about it, is pretty silly considering you wear them to sweat in). But Amazon has a great affordable alternative to Lululemon's popular Align Tank, and it's on sale for less than $20. Get one in a range of colors.

"I own one of the Lululemon Align tank tops and this fits exactly the same," said one shopper. "I do prefer the padding in this tank much better. The length is perfectly cropped, right around the belly button. I've since ordered more in other colors."

"I like to refresh my bed pillows at least once a year, and this comfy set has become an all-time favorite for my bedroom and the guest room. I've even had houseguests comment on how luxurious they feel! They're super fluffy and really feel like those you'd find at a five-star hotel."

Pick up this top-selling personal-sized blender while it's 35% off. The compact gizmo comes with two small blending cups that double as drinking cups for smoothies, protein shakes and more. Of course, you can use it to create sauces and soups as well.

The Fire 7 costs a fraction of what you'd pay for the equivalent iPad Mini. It has a 7-inch screen, weighs about 10 ounces, offers 10 hours of battery life and has a clear camera for video calling. Even better, it's on sale for its lowest price ever.

"Works great," shared a fan. "I use this mainly to read Kindle books and search the internet. Has a great battery life and had zero problems with it!"

Keep warm with this battery-operated heated vest. You can wear it on its own or under a jacket for added toastiness. It provides three levels of heat, and the battery lasts for up to 9.5 hours on the low setting and three hours on the highest setting. It has a relaxed fit and comes in seven colors.

One five-star reviewer shared: "I walk the dog every day and live five minutes from the Atlantic Ocean, so we always have wind which gets very cold in winter. This vest, which I set on the lowest setting, keeps my entire neck, back and torso warm. I recommend this product highly, it is money well spent to keep the core temperature warm while out in the elements."

Hate vacuuming? Get this Shark robot to do it for you while it's on sale over half off. Some highlights: It cleans in neat rows so it won't miss a spot. You'll get up to 90 minutes of cleaning on a single charge, and if it isn't done when the charge runs out, it will pick up where it left off after some rest. And it can go just about anywhere: Use it on carpet, tile or hardwood floors.

"This little guy does a great job," shared a shopper. "Easy setup, cleans the first floor in an hour and a half and leaves everything spotless. Its amazing the amount of debris he picks up — highly recommend."

Brighten your smile in as little as five days' time with this set. Simply use the pen to brush the solution onto your teeth, let it dry and sit for 30-60 minutes, then brush it off. It can help remove coffee, red wine and other pesky stains. 

"My teeth have constant coffee stains, so I always need some form of whitening. I’ve been using the Crest Whitestrips, but didn’t feel like I had been achieving any results," explained a shopper, adding that after just four days: "I think the results are subtle but I can definitely tell a difference. My husband even noticed which we all know is a big deal. Will purchase again!"

You probably know Solawave for its viral red-light wand, but the brand also has an LED mask that combines red light therapy and near-infrared light therapy. It's FDA-cleared and comes with eye protection, though it's minimal (just some small silicone blockers around the eye holes). You may still want to invest in some blackout eye protection and keep your eyes closed during use. Buy it's portable, holds its charge for a long time and is an easy way to get the red light therapy dermatologist treatments at home. 

Need help with your squat form? The Row-N-Ride can help. Place your feet on the pedals, sit your butt on the padded seat, and hold onto the handlebar while you bend your knees like you’re sitting in a chair. Then, use your glutes, legs, core and arms to pull you back upright. Squat all the way down, or if you want to go easier on your knees, adjust the seat to stop at a higher angle. There are also three resistance bands you can add to increase intensity. When not in use, the machine folds flat for storing away in a closet or under the sofa.

"I love this exerciser. It really gives you a good workout," said one five-star fan. "You can adjust the bands to your level of fitness. The exerciser does not take up a lot of space and it's extremely quiet. There are a lot of YouTube videos available for your workout and workout and dietary info are available on the [brand's] website. This exerciser will provide you with an outstanding, low-impact, muscle and cardiovascular workout."

Nearly 5,000 Amazon shoppers rave about this shampoo in the reviews for adding volume and body to their precious locks. It contains biotin and collagen for targeting the roots to help you grow thicker hair from the start and make your current strands perk up. 

"I'm a 'senior citizen' who recently noticed changes and thinning of my hair," explained one user. "I’ve only been using it for about a month, but surprisingly I do notice a change. It’s a little early to proclaim this a miracle product, but my hair is thicker and more manageable, and I do not notice the same amount of hair loss. Hopefully, this trend will continue, but in the meantime I am impressed."

This mask heats up as high as 107°F to deliver warmth to the areas around your eyes. It can even play calming music via Bluetooth.
