I'm in Edmonton, but must go out of the city to find a BBV that takes trade-ins. Some weirdo city bylaw, supposedly, yet EB Games does it all over Edmonton!
Anyway, just outside of Edmonton is St. Albert, and I've gone there a few times to trade in DVDs and games. Was there this past Thursday thinking to possibly trade in some games on this 'trade 3 360 games or 4 others' deal, but all they would let you trade towards was some PS2 game that I wasn't that keen on at the time. The kid there said the titles change & I should phone back, although it's also possible it's more for PRE-ORDERS of games, not currently shipping ones.
Best to phone your local BBV until you find someone who actually knows about the promotion & see what's up. It's easy to find discrepancies between two BBVs that are near to each other!
