Man, gamestop trade in values are a bit absurd! (ps4 games)

[kyokusanagi]

I always trade staff in gamestop, but only when they have the 50% and I'm a pro member so that's 60%,new games you have 30 days and you get 30 dollars on credit, and this cases games like shadow fall sell it in ebay , problem is you have to pay 10% to ebay , games like xenoblade chronicles you can sell it for 70 dollar in ebay.
