I bought 10 of these bags in 2007 and they've held up to weekly grocery shopping, along with lugging stuff to work/school/picnics/etc, and being washed at least once a month, and they're still totally usable! I'm ordering more because mine have seen better days. They look kind of dingy/dirty even when they're clean (I originally had the white/red bags), and they have some sort of latex type lining on the inside bottom that is wearing thin in patches, so I think it's time for new bags. We DEFINITELY got our money's worth with these bags ~ 6 years! I'll still use them as a back up when I have the big grocery trips for holidays, parties, etc,  and need extra bags. They're the perfect simple basic bag for groceries, I like that they aren't humongous because I don't like my bags to get too heavy. Durable, washable, lovely!
