I bought a shopping cart cover from Meijer and I hate it. It's an off brand. I went to use it at Sam's and does not fit. I was thinking of getting the bright starts on they have at babies r us and Target and wondering if anyone knows if that one would fit at Sam's. They probably all fit normal carts but I know Sam's has the big ones. I just left him in his infant seat but soon we're going to have to buy a new car seat and have to put him in the shopping cart so I need to find something fairly soon. Plus I'm sick and tired of carrying him in his infant seat as he's 16 lbs already.
