You need trash bags. Everyone needs trash bags. But it sucks to spend a bunch of money on something that is, by definition, going straight into the trash. Amazon makes its own trash bags now (of course), and you can get a box of 200 for just $16 right now, about $.08 per bag. Even at that price, they’re not bargain basement quality; they have great reviews, and draw strings for easy closing. Just be sure to clip the 20% coupon so you don’t throw away money unnecessarily.
