49 Cool Things Under $30 That You'll Get A Sh*t Ton Of Use Out Of

We only recommend products we love and that we think you will, too. We may receive a portion of sales from products purchased from this article, which was written by our Commerce team.

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.
