I went to pick up a copy of Odin Sphere today on Amazon, noticed there was one factory sealed for £38. I messaged the seller, and asked for a photo of the front and back cover to make sure the game was in English (as in the cover and manual). He replied right away, with a picture and a full description. Happy enough, I was willing to make the £38 purchase for a sealed PS2 game... Lo and behold went back to buy it... He ramped up the price to £50...
Moral of the story is... Don't contact sellers, or so it seems anyway...
