I have the metal clips that I use for my keys to hook my keys on my purse and one for all those little cards at the store for discounts and points. well I use the to hook my purse to the cart also the metal they see the child strap is hooked and can cut it but the hooks look like they are just hanging from my purse with the keys. you grab and the cart comes with you.. worked for me at wal mart.........the look on the face before she ran was great......
