I agree with Dorrie, I know the walmart where I live they hire people that's not mentally able to hold down a job any where else to bring in the shopping carts. I do put them into the cart corral that way it want be to hard for them. I also, grab a cart on my way into the store. I know that the Artlady is right if its at a store where they have to have a cashier go and get the carts. But, with our economy like it is people need a job no matter how small it is.
I use the containers as a holder for my thread crcochet. I have a couple of them attached to my craft table. This is what I do with it. I take a nail and put a hole in the top of the lid sit my ball of crochet thread on the pindle and run the thread through the hole and I don't have to worry about my ball of yarn rolling all around the floor or my crochet bag. I hope this helps you.
