Thank you, OP!!! They had four of 'em at the store I just went to, and it looks like you may be able to find them for less than $30, too (YMMV): both PS3 versions had a green sticker, so I brought one up to a couple of the game reps at the register and asked what it was for. They said it meant I could haggle the price with them. I asked to get it for $10, he said no and offered it to me for $15, so I bought it for $15! SO happy, especially since I couldn't find one at TRU. They were super nice and fun to talk to, too, so extra brownie points for my Best Buy.
There are 2 XB360 and 1 PS3 versions left at the Cambridgeside Galleria store, and apparently anything on that shelf is "haggle-able" merchandise, so have fun, CAGers!
