Stanley tumblers are a rare 25% off, plus 9 more of the best sales to shop today

Scuzzed-up bathroom? Grimy tiles? Never fear, the Khelfer is here. 

This hydrating serum with hyaluronic acid is backed by dermatologists, including Dr. Joshua Zeichner. He served on the external advisory panel of dermatologists who had access to the development and research of the serum and validated L'Oréal's claims. 

"Hyaluronic acid is a humectant ingredient that pulls in hydration to the skin to plump and moisturize," Zeichner tells Yahoo. "It acts like a sponge and can bind to 1,000 times its weight in water." He adds that improved hydration can minimize the appearance of fine lines and boost skin's radiance. All it takes is a few drops in the morning and night, he says.

This iconic bronzing powder, specifically designed for mature skin, contains color-correcting pigments to help even out your skin while leaving you looking natural, not like you've slathered on a ton of product. The formula self-adjusts to match your skin tone, so you don't have to worry about it being too warm or too cool as long as you select your closest shade.

The product itself is actually, truly baked: The pigments are heated on terracotta tiles for 24 hours, giving them a unique consistency that offers the convenience of a powder with the coverage of a cream. They fill in pores and create a smooth finish but won't settle into fine lines.

Hate vacuuming? Get a robot to do it for you! You can use this high-end Roomba to clean your whole house or select rooms. It can go just about anywhere — use it on carpet, tile or hardwood — and it's smart enough to avoid sucking up rogue socks, shoes, computer cords, etc.

"I have two German Shepherds, which equals a lot of fur, therefore we have four Roombas. Yes, four," said one loyal shopper. "This one does seem to get stuck under furniture more than the other two. However, it gets over things better, runs quieter and vacuums both the carpet and hardwood just as well if not better. So, I bought a second one. I highly recommend it. I have all four scheduled to run every day, they work well with Alexa and I truly have no complaints. If I needed a fifth roomba I would 100% buy a third of this model."

Behold: Stanley's famous tumbler is a rare 25% off in select colors on its website and at select other retailers, including Amazon. If you don't have one of these big cups yet, you should know that it's made with recycled stainless steel and fits into most car cupholders despite its considerable size. Most importantly, however, it can keep drinks cold for up to 11 hours (or longer, fans say), thanks to its double-wall vacuum insulation.

"Worth the hype!" said one happy, hydrated buyer. "The Quencher is everything I expected — durable, well-made and perfect for daily use. The cream color is gorgeous, and the stainless steel insulation keeps drinks cold for hours. The handle is sturdy, and it fits perfectly in cup holders, making it great for travel or everyday hydration ... wish I could afford the entire collection — I'm obsessed!"

Going on a long trip? This neck pillow is adjustable, breathable and can help you get some shut-eye on your journey. It's made with soft memory foam to support your neck and head, while also remaining comfy and cozy. No wonder it's Amazon's No. 1 selling travel pillow. 

"Very comfortable," said a shopper. "I started traveling a lot for work so I bought this to get comfortable on the plane when I sleep, and it doesn’t disappoint. It even has zippers to wash it properly. It provides pretty good neck support when I sleep and the memory foam makes it well worth it."

Ready to transform your shower into a spa-like experience? Made of chrome and stainless steel this lightweight, easy-to-install (no tools needed!) shower head has a reinforced stainless steel hose for super-flexible reach and mobility. More than 60,000 shoppers rave about it.

"Shockingly good for the price," wrote a five-star fan. "It looks good, works flawlessly, and doesn't leak. Having a proper showerhead makes the apartment MUCH more livable. It was a high-impact upgrade at a very low cost. Besides making showers more comfortable, having a movable showerhead makes cleaning the shower immeasurably easier. I'd consider it a must-have."

"We received our W2s digitally and early this year, so we decided to buy this TurboTax download and go ahead and file," said one customer. "We like how TurboTax imports our information from last year when we filed. That saves some time typing. I like how it updates your estimated return or if you have to pay, how much as you go, filling out the information. Including state filing is helpful too for those of us living in states that have income tax."

This Insignia is ideal for cord-cutters since it turns streaming into a cable-like experience. And it's a great deal — this is the lowest price it's dropped to all year. 

A few highlights: Alexa is included in the remote, so instead of endlessly scrolling through the guide, you can just say, "Alexa, play Your Honor" and she’ll make your wish come true. Compare this to other TVs that come with Roku inside but lack voice assistant features out of the box. The TV also has vivid colors and exceptional high-definition picture quality, rare at this price point.

Over 9,000 customers have left a glowing five-star review at Amazon. "It's even better than I could dream of for the price," said one reviewer. “I was amazed at the quality of the picture. Went to F1TV for the ultimate test. Outstanding! Even better in the evening for outdoor movie time. Of course, it is not a $5K TV, but the picture and sound were way beyond what I expected for the price."

"I bought the 50-inch model, and my roommate bought the 43-inch model, and we're both awestruck," wrote an experienced gamer. "The picture quality is fantastic, the audio quality is awesome and it's not too heavy."

We love our Patagonia puffer jackets, but as the temps start to rise, we're shedding our thicker layers. This classic is water- and wind-resistant, lightweight, packable — perfect for running, hiking, cycling or just staying dry on a rainy day. Grab one while it's 30% off in six colors at REI.

"This is my second Houdini. My first, which I have loved for several years, is lost (aptly named, right?), so I needed a replacement," said a loyal fan. "I love to throw it in my bag when I travel. This jacket is perfect for hiking or walking in wind and/or light rain."

If you're gearing up to put away your winter coats and chunky sweaters, we're with you. But you'll still need a little something to keep warm on chilly spring days. Try this top-selling cardigan from Amazon, up to 40% off in over 20 colors. It has a tunic-like length that makes it great for wearing with leggings, and it has pockets on the sides. 

"I love this sweater! Quality material, warm, soft, yet durable. The fit is nice. Not a bad price," said one of the 7,900 five-star fans. "I'm going to buy another one in a different color."
