The 20 most popular October Prime Day deals with our readers, from dog treats to headphones

It seems like our readers are big fans of leftovers, as this 42-piece Rubbermaid set is currently the most popular item they've purchased this Prime Day. It has a variety of sizes and accompanying lids, and it's on sale for only $20.

Crest's 3D Whitestrips are always popular with our readers during deal days, and this Prime Day is no exception. This kit comes with everything for a full 20-day treatment. You also get two sets of express strips for more last-minute whitening sessions. The set is 35% off at the moment.

We have a lot of dog lovers among our readers, so it's no surprise they've been cashing in on deals to spoil their pooches. Made with potato starch and cheese, among other ingredients, Chewmeter's dog treats are rawhide-free. While not the lowest price we've seen them sell for, the chews have been above $20 for most of the year, so now is a good time to buy if your pup loves them.

Continuing the theme of dental care, lots of our readers are cashing in on a stellar deal on Waterpik flossers. We think the Waterpik Aquarius water flosser is the easiest and most effective way to floss, removing up to 99.9% of plaque from treated areas. It's also more effective than floss for improving gum health, and gentler on sensitive gums. Right now it's down to $45, the lowest price we've seen since 2020.

The Casper Original Pillow offers the loft and support that side sleepers need but with the soft and fluffy feel of a down alternative. Right now, you can get the pillow for $42, the lowest price we've ever seen it.

Kindle Unlimited, the subscription service that has a massive library of e-books, audiobooks, and magazine subscriptions is deeply discounted this Prime Day and our readers have jumped on the deal. The service typically costs $10 a month but Prime members can now get their first three months for just $1 total. That's $29 off the regular $30 cost. 

Apple's latest AirPods Pro have vastly improved sound quality and better noise cancellation than the originals. This is only a slight discount, but these debuted in September, and Apple rarely drops the price on its new devices.

Over $100 is a lot for a garbage can, but Simplehuman's are stylish and functional. This 45-liter stainless steel model contains a pocket for liner bags, and the lid smoothly and quietly opens when you step on the pedal. You can save $40 during the Prime event.

The Braun Series 7 is able to "read" the density of your beard, automatically adjusting its power to give you the closest shave ever. It's the lowest price we've seen it all year.
