[quote name='Ulchie']So theoretically could we get Wolfenstein, trade it in cause it's a GG, and then get Halo 3 ODST, and then trade that in because it's a GG too? Or can you not combine offers like that? I'm just wondering because beyond the singleplayer, ODST offers me nothing and we all know how short ODST will be. At this point I'd rather use my GG on Halo 3 because I know 3 weeks after release I'll never touch it again, and I really don't care about Wolfenstein but it's a free rental so that's the only reason I'm bothering with it.[/QUOTE]
Yes, you can do that. When you return Wolfenstein you'll get $69.99 to spend on whatever you want. And that could be an ODST pre-order. And then return that for 69.99.
