Guess what happens nearly everytime at JB HI FI.
I trade in the games, THEY DO NOT EVEN OPEN THE CASE TO SEE IF THE GAME IS INSIDE! I was watching the dude, he just wrapped all 3 games in special tape then put them in the trading box and did not even check to see if it was in good condition or if there was a game in there.
Same thing happened when I went to exchange my PS3, they did not even check the box. I could of put telephone books in there and walked away with two PS3's and they couldn't catch me.
They are very very slack if you ask me, and if you are interested in trading in some imported games I say go for it.
