Other Plastic Bags?

What the heck do I do with all those other plastic bags? I applaude the grocery stores for taking theirs back - and I do bring them back. And, anything that can be recycled does get recycled here. (We're doing great on that!) But, things like bread bags or pretzel bags? What do other people do with these? There are only so many things I can save - I mean we go through probably two loafs of bread per week! Ideas? Suggestions?
