After I got my order confirmation for the card, I sent a reply correcting the zip code so they wouldn't have any trouble charging my credit card. I also asked if it would "really take 2-4 weeks" to get the card. They responded by saying "Thank you for the info. We will try to get your order out earlier."
Anyway, I thought that was interesting. We'll see how long it takes. I'll keep you all posted.
EDIT:
By the way, e-mail correspondcence will come from a place called "Althon Micro" (no that's not a typo - it's Althon, not Athlon). I guess ATI outsources the fulfillment for the trade-up deal.
