I've mostly bought online and just recently started calling a store to order and ship to me... The other day when I bought something in person at a store and gave my CC, the SA asked if I still lived at the same address and quoted my address to me. Kinda surprised me! If I had used a different CC would they still have known it was me? So would they also be able to see everything I've ever ordered -- and returned as well? Just curious is all! Thanks!
