It is also important to watch carefully to avoid a switcheroo where they keep your activated card and substitute an unactivated card, at any store or management office where cards are kept behind the desk (or where surplus cards are available there). This is not as much of a concern at grocery and other stores where the cards are in a public area and the Customer Service desk cashier would have no available cards to do the switcheroo with, unless you are a regular and he/she plans ahead.
