Online shopping is fun, but it’s even better when you end up with something that’s pure genius. I’m talking the kind of “genius” that makes your jaw drop, or the kind that makes you wonder why you haven’t bought that product sooner. Luckily, there are countless amounts of cool things on Amazon that are smart as hell — just like those — and they all serve useful purposes. Plus, the ones included on this list are under $30, which means you don’t have to break the bank in order to fill your cart.

Case in point? The cupholder designed for your bathtub. Not only does it easily adhere to tile and other smooth surfaces, but it can also fit everything from beer cans to wine glasses. But if you're looking for an even smarter purchase, there's also an alarm clock with a built-in wireless charger so you don’t have to fumble around for a power cable as you drift to sleep. Oh, and I can’t forget about the strap that’ll help you do two-person stretches by yourself. It’s genius, right?
