I Pre-Ordered God Of War 3 back in December for $89.99. I now see a price for it on Amazon for $136.99. Since I pre-ordered it for $89.99 do I now have to pay the difference? I checked the website and it mentions if prices drop they will pay the difference, but nothing about if prices rises. Also, I think the $136 price includes the God of War 1 and 2 game, but Amazon might have messed up and just forgot to mention that. However, they don't have the $89 price on there webpage at all.
