What could I trade in at gamestop to purchase an htc vive

[BurgerKingHotDogWater]

So lately since the vive's price reduction I have been trying to get some money to buy an htc vive but I have had no luck I'm trying to sell my psvr a bunch of xbox 360 and ps3 games and some ps4 games so what could I do to get 600$ from gamestop trade credit since most of that suff will be considered pocket change from gamestop.

Gamestop will give you as little as possible. Better off selling via kijiji, letgo or some other buy/sell site.
