A few days ago I got a 60% off promo code e-mail. I've been trying to use it for BF3remium edition. after entering to code the screen refreshes, but no change in the price shows. I'm worried that if I continue with the order that I'll get hit with the full price of the item. I've typed the code as it appears in the e-mail. It expires oct.31st. Am I doing something wrong?
