I used to work for eb games, in Canada, and I know how to abuse the system. My friend, who is a manger at eb, called me with the weirdest news. 
Tekken 6 was selling for 10 dollars new and trading in for 9. By using the trade 2 deal I was able to trade all of them in for 100 dollars. 
This is the real reason Gamestop will go out of business. 

Uh, can you actually be more specific about how you did this?  What's the "trade 2 deal", for example? 
 
It's insider information that gave you this possibility, but it works.

Please send me a copy of Tekken 6.
