I'll check when I get home for a promo number. I was amazed to see the mailer, too--I thought it was for the triple miles deal this summer because it is the same color scheme and stuff. I was targetted for the summer promo that ends today with a threshold of $650, but this one clearly says my threshold is $250, that you don't have to register ("you're already registered" or something), and that it is from 10/1 through 12/31. I did a search last night before I started this thread and couldn't believe I was the first one to post this!
Tonight I'll post the exact terms--should've stuck it in my briefcase!
