cmouse01:And don't forget about crocheting them into floor mats, tote bags, etc.

Just when I've started to find uses for all those extra bags, they'll stop using them...
You can alway crochet with plastic bread bags, plastic bags they cover the newspaper with, plastic bags that hold produce or other products, plastic bags that cover your dry cleaning... makes me wonder why they have it in for shopping bags and allow everything else to go on.
The main thing I use them for is to line trash bags in the bathroom, kitchen, office and bedroom. If I have to buy trash bags for that, what have they gained? (Except my money!)
