So I made an embarrassing mistake that will cost me with Stouffer's this month. At the beginning of the month, I pointed out that Stouffer's was offering double points per code after you entered eight in October. So I went over to Listia and loaded up on codes to break the eight mark. One of the guys selling codes on Listia noted that you get double points for every code starting with your second, but I just figured he had made a mistake. He hadn't.
Turns out that the promo was targeted differently to every account holder. Our household has two accounts, although one gets used more frequently than the other. I didn't even bother to check the other to see if the promo was different. Sure enough, that account got the bonus points for the second and beyond. Ouch. I cost myself 140 points by not paying attention.
Bottom line: If you get a promo and have multiple accounts in your household, check each account for the terms.
