If you read the end of the promotional box, you will see it says "Limit one per customer." And if you decide to do what M. Troiani says, do it at your own risk, because Amazon would retain the right to terminate both of your accounts, and cancel both of your orders, if they feel you are trying to "dupe" the system. Technically you're not supposed to have multiple Amazon accounts, but I guess it's up to you if you wanna take the risk.
Shadow Shogun: You probably won't get it automatically, but you might have a chance if you contact customer service. Last year I ordered the standard version of Black Ops on Xbox 360 for myself, and the Prestige edition on PS3 for someone else, in separate orders. Initially I only got the credit for one order, so I contacted customer service and argued that although they were technically the same game, they were different versions and not interchangeable, so they should be considered two different items. After a couple of days I got the credit for both orders.
what are you trying to do? buy say 3 and get a total of $60 in credits and then sell the games for full price or even at a discount of say $50 apiece. So for example
$55(game price bought at)-$50(resell unopened to say a friend)=(-5)net cash+$20 credit==(+)$15credit(free money)
So a little hustle for a nice little profit. Your friend gets a good deal and you get a little spending cash on amazon...build up money buy more games and so forth.
Not a bad idea if you work at gamestop or a place like that. A person walks up and says I want to buy portal2 from you for 60, you say hey I can sell it to you for 50 legit copy....ok so 15 people show up and all take the deal you would now have made $225credit for amazon
SOOO I think this is what the person really is asking about....Can I but multiple copies to pull this off?
No, I think he just wants a copy for his friend and himself. Not to mention it wouldn't be very helpful to him, because the only way he could get multiple credits is ordering on multiple accounts...and since the credit is non-transferable that would leave him with 15 accounts that each have $20 on them. Don't really know what you're going to buy with $20 (15 times) to make that worthwhile. Not to mention I'm sure Amazon would catch on if he was using the same credit card/house address for each order. MAYBE if he had 15 friends willing to let him use their credit cards and ship the items to his house, he could pull it off...but it still would be almost useless having all the credits on that many different accounts. That, and the fact that if Amazon does catch on, and cancels all the accounts before you can use your $20 credits, and you have already sold all the Portal 2's at a lower price ($50 as you say), then you would be out about $90 considering you choose Release Date Delivery, and there's no tax in your state.
Really seems like a lot of work and not really worth it.
