Gamestop has been really dropping the ball the last couple of years, on my last two pre-orders I didn't get my pre order gift. The first time it happened I was a little mad but no big deal. The second time it happened with Xenosaga III, I was pretty fucking pissed and let them know(they got 20 preorders in the store and only got 5 preorder gifts total, WTF?). After they didn't give me my last one they asked if I wanted to preorder Okami right after I told them I wasn't preordering from them anymore, how fucking stupid can you get? To top it all off they didn't even call me when the game had come in like they are supposed to with preorders. I don't have to preorder games, they rarely run out, but I only preorder to get a goodie and when I can't even get that, why give them my money? I get a 10% discount on everything at work so I'll just be buying things there instead of hoping for a preorder gift.
On the topic of reselling games, I have only done it a couple of times. My brothers and I sold our Jaguar that we found at a garage sale for $20 with a bunch of games, after we got bored with it, we sold it and the games for like $60 store credit. The other time I did it was with a bunch of shitty PS1 games some jackass friend of my moms ex-boyfriend left over one time and wouldn't pick up. I got about $20 for like 8 games.
