Not everyone reuses ziploc bags or the like, but consider the potential. Each little baggie costs about .07, which I realize is not a lot, but let's say you reuse enough bags in a year to not waste 100 bags. That alone accounts for $7.00. Not much, eh? True, but one small habit started soon spills over into many habits that pile up. There is an old saying that I read in Isabella Beetons Book of Household Managemnt" that I love but will Americanize, "Take care of you pennies and your dollars will take care of themselves" (she used pounds and farthings I think )
I do have a few rules about reusing bags though, never after raw meat of any sort, allow to thoroughly dry after washing, when you fill it with water and the leaks resemble a sprinler system, either throw away or use for crayons and markers only.
Any of you have any good bag reuses?
I reuse store bread bags for homemade bread too.
I keep ratty reused bags in the car for trash collection.
In the summer I also keep spare bags for wet bathing suits,etc.
