happened to me as well. forgot i had boxed soda under the cart. realized it after emptying the bagged groceries into the car. took it back in apologized and paid for it. no trouble, no problem. been shopping there for over 20 years.
we have one ! my nephew built it as a joke, not “full sized”, no working door, just décor, if you will – it’s in the corner of backyard w/ the morning glories
we used to stick the pennies to the track w/ chewed gum to keep the pennies in place – usually worked albeit a bit messy
