1. It's an offer - no coupon needed. $10 bonus added per 2 PS3, 360, or Wii games traded in. Games that have trade values under $1 (2006 360 sports games and Burger King games) excluded.
2. No membership needed. If you've got an Edge card, it'll add 10% to the trade price. If you don't, well, it won't.
Thanks. It would be great if the OP could edit his post with this so other newbies won't ask questions that were already answered. Oh, and Dexter is my favorite television series of all time. I won't trouble the thread though with an off-topic conversation about it, haha. No worries.
