Well, the crooks have found a way to rob you of your Gift Card balance.
If you buy Gift Cards from a display rack that has various store cards you may become a victim of theft. Crooks are now jotting down the card numbers in the store and then wait a few days and call to see how much of a balance THEY have on the card. Once they find the card is "activated," they then go online and start shopping.
You may want to purchase your card from a customer service person, where they do not have the Gift Cards viewable to the public.
