well mine was rather complicated, i bought 4 cheap games from play-asia, total came to about $75 or so, traded them in at jb-hifi for 2 copys of metal gear solid 4, kept 1 and traded the other at eb games for $105 store credit (a deal they had at the time) and got BF:BC for $79 (price match) and i also got a pre-owned copy of motorstorm. All for a $75~ outlay, complicated, but it works.
