If you didn't read the fine print for RR, and if something is in there relating to the discount offer and 'one per household/account/email/whatever', I think EB has a very good case about removing the credit and charging you full price, since you weren't supposed to get multiples anyway. Yes, you could argue the RR site shouldn't have let you, but ultimately, if you clicked 'yes', you are saying you agree to the terms. They would not be totally amiss in calling it fraud, especially if someone from EB or RR were to wander over here somehow [like, checking the affiliate links] and see people, well, colluding to defraud, which I'm pretty sure is illegal.
Should they just cancel these orders, rather than just changing the charge amount? Probably. But since the original amount of X-10=OrderTotal was calculated fraudulently, they may have the right to do that.
Scrubking: Yep, I could see that...and don't forget, not only is CAG home to conspirators, but it *has a curse word in the name*! Film at 11!
