On the fence about this here - had 1 experience over on GAF, and it didn't turn out so good. I know it's the gift of giving, but to give an item I had so desperately wanted myself to someone else, and receive a pre-owned copy of LittleBigPlanet Karting, with a $4.99 tag still on, 2 months late? Hurt a little :( for those participating though, all the best! I'll be swaying too and from until deadline, that's for sure.
Sorry to hear about your experience. You can never 100 percent tell how it's going to work out, and I'd be annoyed too if that happened to me. Hopefully you'll have better luck this year.
