Wasting money is easy, but you know what’s way harder? Saving it. And since my bank account has been looking a little worse for wear lately, I’ve made a deal with myself: I can still buy whatever I want, but only if it’s a cool, affordable Amazon product I’ll get a sh*t ton of use out of.

That might sound a little restrictive at first — but luckily for both of us, Amazon has a massive selection of useful items that won’t break the bank. Case in point? The mandoline on this list that helps you slice up everything from cheese to vegetables. Not only does it help you get dinner on the table quickly, but the blades are also made from stainless steel. And don’t get me started on the flash drive designed to work with smartphones. With 128 gigabytes worth of space, you’ll find yourself reaching for it every time you need to clear up some memory — a must-have if you love taking videos.

Whether you’re looking to save money or spend it, you can’t go wrong with products that you’ll get a sh*t ton of use out of. So what are you waiting for? Everything featured here is priced at $30 or less — keep scrolling to see some of my favorites.


This Knee Pillow Filled With Soft Memory Foam

Unlike some knee pillows, this one is filled with soft memory foam that contours to the shape of your legs.

Tired of always having to buy new lighters or refill the fuel? Then you’ll definitely want to check out this electronic one.

A Non-Stick Skillet Made Without Any PFOA

Some non-stick pans are made with PFOA, which can flake off into your food as the pan ages — but not this one.
