So today I placed an order for Dead Rising from GS.com. When I was checking out I used CAG16 and my edge card, witch brought to total to 13.xx, which was fine, and the 2.99 for shipping, and 1 for tax. So I was cool with this, seeing as since I'm not quite 17 I can't buy it in store, but then when I get my invoice and the charge on my card, it say $19.xx. WTF is that? Why did they randomly NOT give me my edge discount AFTER i checked out and it WAS there......Could I go into the store after I recieve my order and get credit back for their mistake? Or am I pretty much screwed?
