They're good for everything. And they only cost sixty cents! I use it, of course, when I go to IKEA, but I also use it when I go to Costco- I don't bring it in to the store, but when I'm loading my car in the parking lot, I put all my smaller items (small for Costco, at least) in the bag so they're easy to unload when I get home. I use it when I do my normal grocery shopping sometimes, too- especially if I've gotten a lot of cans. You could use them as a picnic basket, even. Or a small tent!
