I read somewhere that the average person uses like 500 plastic bags a year and each one gets used for maybe 12 minutes. That really stuck with me. So dropping $60 on a set of sturdy bags that you actually use sounds like a no brainer compared to that waste. Plus most stores give a 5 or 10 cent credit for bringing your own here, so it adds up quick. Did you get the ones that fold into a little pouch or the big canvas totes?
Haha my buddy bought the folding pouch ones and forgot they were in his backpack for like 3 months then pulled them out at the store covered in old granola crumbs. Still works though.
