Wanted to update everyone:
Just got back from BB, they will price match, however, they will call TRU to confirm that the games you choose are in stock at your local TRU. Important to note if you want 'Demon's Souls' or other M rated games that are slightly obscure.
I walked out with 'Assassin's Creed 2' and 'Left 4 Dead 2' for the grand total of $64.64 (inc tax) pretty happy.
In a strange twist of events I also discovered this little tidbit I thought i'd share: If you do the deal on 2 copies of MW:2 at TRU you pay $60.
Right now Gamestop are doing an additional 50% trade in on anything that goes towards GOW III or FF XIII. MW:2 trades in for $30 at gametop right now, so 2 copies plus the extra 50% you get $90 trade in credit towards either, or both GOWIII or FF XIII.
So, I did this deal at TRU also and with Edge card at Gamestop I've now paid of GoW III and FF XIII for the grand total of $81.
