I generally use the smaller grocery cart, and even the smallest of these bags will not fit. It's taller than the cart so it won't sit flat, plus the rods stick out so far on the sides that I have to be careful not to catch them on displays. I was particularly interested in the insulated one, but that's even bigger, and none of them will stay open until you have lots of items in there. I also tried using them with a regular sized cart, but you really need to use all four and fill the cart with them. If there’s just one or two, they slide forward on the slanted edge of the cart and squash together. There are only two of us, so I rarely buy enough at one time to need all four bags, plus I don’t care to switch to the larger cart. So I'll probably just donate them and maybe someone else can find them useful. I should have paid more attention to the dimensions and logistics before ordering.
