I'm tempted to trade in my disc-only for Dragon Age and just keep the Collector's tin and such, and just re-buy it when the inevitable "Game of the Year Edition" pops up.
I can't seem to get any of the CSRs to honour the $30 trade credit on Brawl. It's always $25.50 in the system and they are unable to do an override. Oh, and none have even heard of this mailer, much less seen it. Weird.
