Amazon's secret coupon page is wild — save up to 50% on Beats headphones and more

A kitchen tool must be doing something right to attract more than 84,000 five-star ratings at Amazon. So what sets this thing apart? Unlike ones where you have to keep pulling a string to slice your veggies, this gizmo gives you a uniform dice in one fell swoop. Plus, it comes with four interchangeable blades if you want to switch up the shape of your produce. It's marked down 50% to $25 with the on-page coupon, so chop chop!

A sweet 30% off right now, this oversized chunky number will be your go-to for the winter and beyond. It's a great layering piece, and we love the long sleeves that extend over your wrists for that extra cozy feel. Get it in more than 20 colors.

One fan wrote: "The sweater is thick, so it keeps you warm. It is also very soft and flattering. The quality is 10/10."

This is one of those items you hope to never need, but you're always happy to have — just in case. The popular pick is just $42 right now thanks to the 40% off on-page coupon. 

"Honestly one of the best investments I've made," one reviewer raved. "It has saved my life on a few occasions. It definitely comes in handy when my kids forget to turn a light out in my vehicle and the battery dies. It is convenient, compact, portable, powerful and functions perfectly."

Save nearly 45% on this popular doodad that'll lighten your teeth — not your wallet. The high-pressure water pulses annihilate stains, food debris and plaque to keep your mouth fresh. Modes include gentle, normal, pulse and powerful; you'll get 30 days per charge.

These have been top-sellers for years — more than 10,000 were bought in the past month alone. The headphones are compatible with both Apple and Android devices and last up to 50 hours on a single charge. That's some pretty impressive battery life! Right now, for a limited time, they're 50% off at Amazon.

"I've owned a pair of Apple AirPods and Beats earbuds, but these headphones are by far the best I've ever owned," one fan wrote. "They do not have noise-canceling, but they have every other feature you could possibly need."

This beast employs two tanks: One holds clean water (and a dash of Tineco's cleaning solution) and the other collects the dirty water that gets sucked up. But, wait! It's a hand vac too: Just push a button to release the upper section, then snap in a crevice tool or 2-in-1 brush tool. (Both live in a standalone storage tray when not in use.) The vac docks in a charger/stand that allows for self-cleaning, again with the push of a button.

"When this came, I had just steam-mopped the night before," one five-star reviewer wrote. "Ran it once and holy nasty water! This thing is 10,000% worth it."
