I don't use bags. Produce goes into the basket/cart naked. When I get home it either goes naked into the crisper drawer or goes into a pastic or glass container with a lid to stay moist. The only exception is the rare instance I am buying lots of small produce like mushrooms or snap peas. Then I use the plastic bags they provide but I also recycle them after use, so at least they don't end up in the trash. But about 98% of stuff I used to bag, like onions, lettuce, broccoli, and celery, is really fine without the bag. I figure I'm going to wash it anyway, so what is a little bit more dirt going to hurt?
