I track deals for a living — today's best sales include Ninja, Hoka and Bissell

Score this multicooker while it's on sale and use it for all your hearty winter meals. This is the best price you'll find on this thing across the web. Everywhere else (including at Amazon) it's on sale for $100, down from $120.

And this baby is worth every penny! It can slow cook, braise, bake, steam, sauté and keep food warm. It has a removable cooking pot inside that's oven-safe up to 500°F, so you can finish your meal in the oven for a crispy top. 

"It's an all-in-one cooker," said one Walmart shopper. "No need to brown something in one pan and toss it into a slow cooker. This has a sear/saute option that makes it so much easier."

Sometimes your comfiest clothes are the simplest ones, like this Hanes crewneck sweatshirt. More than 43,000 Amazon shoppers give it a five-star rating, and it's on sale in a range of colors. (Of course, the price will vary by color, but this navy is 50% off!) 

"I love this sweatshirt! It is so soft and a great fit," said one shopper. "The quality is superb and comparable to more expensive brands. It is very comfortable and I will buy a few more in different colors. Highly recommend!"

Dick's Sporting Goods just marked down Hoka's Bondi 8 running shoes (for women and men, BTW). Grab this top-selling, comfortable style if you're looking to increase your step count. They're on sale in a wide range of colors, but we love this white and blue shade — add 'em to your cart quickly before your size sells out.

"I bought these shoes for standing on my feet for long hours. They are a 10/10!" said one reviewer.

Your stained carpets and upholstery are no match for Bissell's Little Green Machine, according to Yahoo home and garden writer Kristin Granero. You can use it on rugs, couches, mattresses and more to bring things back to that "fresh from the factory" feel. Just fill one of the tanks with a mix of water and cleaning solution, turn it on and use the hose to start scrubbing away stains and other messes. The dirty water goes into a separate detachable tank that you can easily dump out in the sink.

I have one of these, and I use it almost weekly on pet stains, food spills and more. Recently, my partner violently sneezed while drinking a glass of red wine on our white couch (true story), but the Little Green Machine got it all out (lucky for him). Get it now while it's on sale, whether you have pets or just live with some clumsy people.

"The muck and mystery liquid it pulled from my car carpet was disgusting and oddly satisfying," said one Amazon reviewer. "Went to show my mother and did a spot in my sister's room and listen, her floor hasn't seen [this] color white in years!"

This compact treadmill is only 3.5 inches high and 39 inches long, so you can slide it under your sofa or bed when you're not using it. It's also only 22 pounds, which is light enough that you can probably pull it out on your own (but just heavy enough to make you sweat a little while doing so —heh).

This handlebar-free tread, designed for walking, goes up to 3.8 mph and shows your speed, distance, time and even calories burned. Also great: It has an anti-slip belt and a strong damping system, so you won't make too much noise. Control it with the included remote. Want to amp up your strength workouts? It also vibrates so you can add a little balancing practice to your exercises.

"If you're looking for a convenient, effective and portable fitness solution, this is it!" said one five-star fan. "This has been a game changer as a busy mom trying to stay fit at home. It's light and compact, but still powerful. I love being able to use the remote control to adjust speed and see how many steps and miles I am walking. It's easy to transport and I can slide it under my bed after use. Easily my best purchase of the year!"

You can never have too many comfy leggings, right? Grab a three-pack while they're under $8 each. You can choose all black, or there are more packs with multiple colors on sale too. Plus, they're thick enough to provide a little tummy control, they're not see-through and they have pockets. Amazon shoppers rave about them!

"Buttery soft," said one of the 3,700 five-star reviewers. "These leggings are of good quality, they are not thin or see-through like the cheap ones from other companies you find on here. They are so soft. The pockets are deep enough to put my phone in all the way and I love the high waist. The top does not roll down. They stay up. I love these leggings."

A busy schedule often means less sleep — and dark circles and puffy eyes. That's probably why Real Housewives of Beverly Hills star Kyle Richards has been seen wearing these Peter Thomas Roth under-eye patches while filming over the last several seasons. These lavish gold patches feel like a treat to wear, but they actually work to firm, lift and brighten your skin.

"I use these almost every morning before work," said one loyal fan. "I've had puffiness and dark circles under my eyes all my life, no matter how much sleep I get. I put these on before my drive to work and my eyes look great by the time I arrive. Big difference in the before and after. Highly recommend!"

Paid for by Wayfair

If you have a lot of clothes and you feel like your closet is packed to the brim, try swapping your plastic and wire hangers for these. They'll give you some added room! Why? These velvet hangers are slim, so you can fit more on the rack, and they hold onto clothes a little better, thanks to velvet's natural friction. No more clothes slipping off or dangling in a messy fashion — just everything hanging neatly in a row. Plus, you can't beat this deal — 100 hangers for $40! 

On Wayfair shopper said: "I like these hangers. I have them in several colors for different members of our family. They do a really good job of holding your clothes and saving space since they are thinner hangers."

You can't put a price on your safety, but this handy carbon monoxide detector is nearly half off at Amazon today. It plugs into the wall and has a 9-volt battery backup should the power go out. You can easily read its digital LED display too. 

One shopper explained their experience using it: "My home's natural gas boiler was over 25 years old and began leaking CO from incomplete combustion issues. This Kidde CO detector audibly alerted me and displayed the current CO level as well as the maximum CO level that it had recorded. Very simple to use and displays basic, yet useful information. I was able to open the windows and ventilate my house to prevent the excess CO buildup from harming us, thanks to this CO detector's audible and visual alerts."

A towel warmer is a luxury you'll really appreciate while it's cold out. Just plug it in, power it on and place up to two bath sheet-sized towels inside. The lid has a handle that makes it easy to get your hot towels out without burning yourself. You can also use this to warm up your throw blankets, slippers, pajamas and more.

"I love this towel warmer," said one user. "I throw my PJs at the bottom, robe next and towel on top. Everything is so nice and warm, at times a little hot if I have it set on the red setting, but overall this is the best little gadget I could have purchased for myself."
