37 Genius Inventions Under $10 You've Never Seen Before

When you shop on Amazon as much as I do, you get used to seeing the same products over and over again. I'm talking bestsellers, everyday necessities, and boring stuff like charging cables. Yawn.

Oh, also, everything is under 10 bucks.

So really, you have no excuse but to scroll through this list and buy something. Not only are these products new and interesting, but they're also super affordable.
