In this case I'd suck it up and forget it .I wouldn't feel too guilty about this P.S. E. is a big manufacturer and 310.00 is nothing to them .Just be glad you got something in return for your own mistake ,most time's these thing's don't turn out this way.
If I can help you out and make you feel better .You can buy the bow that you really want now with some added cash of course .If this was the other way around do you think they would feel bad . The money's better in your pocket than theirs.
