I pre-ordered from AT&T as well (BTW, you can join my tracking thread here). I think there is a web site, but the last time I got a phone from AT&T, I did this: Once the phone comes in set it up, go into Shop Samsung app and check your inbox, a link to the Promotion should be waiting in there. Once you enter your info and submit the receipt, they email you a coupon in a day or two, which you then you at the checkout on samsung.com or Shot Samsung app.
