IJust Got An Email From Amazon Denying This....
Hunh, I got an email from Amazon confirming the credits I was getting back. Not sure what exactly you did but I just used the normal interface option to request a return. Chose other as a reason and listed "I'm extremely dissatisfied with this product." Used their pre paid mailing label and 2 days later got an email confirming the details. There was a $5 charge taken out for mailing fees which is fine. I was honestly expecting to get less back since I got a $10 credit issued to the account. Maybe that will be corrected later.
If you're unhappy with this and want a refund, go ask for it. The worst they can say is no.
I wouldn't be surprised if they consider your purchase history and make the choice on a case by case basis. If you get denied I suggest either selling it via ebay or amazon or possibly trading it at Goozex. (can earn an EA!) Seems to be getting approx $42 on amazon if you sell it there. I would guess you'll get $35 out of that if that helps....maybe a bit more.
