I am getting trouble from Staples as well now. Went to the cashier with 5x$200 cards and $200 worth of genuine (non GC purchases) and the Asst manager asked for a second form of ID and call the cc for verification. No thanks!!
Store managers in same location allowed me to buy $1500 worth of transactions in one swipe. Such a pita.

Can any pin-enabled $500 GC from RX stores be loaded on the bird? Less points but less hassle from cashiers as well.
