I have these in the trunk of my car for when I go grocery shopping and don't need to buy a lot. They work pretty well and don't take up a ton of space. One caveat would be that I would not recommend these for heavier items, the bottoms are pretty flimsy so you wouldn't want to put a bunch of canned food in one. Other than that, these are good for small shopping trips, I just put all three in my cart and place items in them when shopping. So far I haven't run into any issues but I'm also not trying to load these up with a lot of weight.
