Wow, I can't believe you found so many Sluggers and M&S. I haven't seen a single Sluggers across 5-6 stores so far. They all sold out around Christmas when they dropped to $9.99.
As for a trade thread, no, I've always just allowed that sort of thing to go on in the main thread as an exception to the usual CAG rule. But if you want to make a trade thread I'll link it in the OP.
I'm not allowed to make a thread in the master list subforum.
And I found a store where they weren't marked correctly. Put them towards Infamous, LBP, GoW Collection and Uncharted. I made an instant PS3 collection of about 18 games for 100 bucks. Pretty ecstatic.
