If you want the card faster call this number for the approval dept a few hours after you apply:
800-480-1870 MF 8AM-10:30PM S 9AM-8PM EST
Tell them you were approved for a card and would like it expedited to you so you can start making purchases right away. They overnighted it to me and I picked up my PS3 yesterday. Got the $100 gift card from WM on the spot.
