Borderlands 2 Ultimate Loot Chest Edition xbox360

[inzombiac]

I've had this since the midnight release. The box is sitting in my room I've never opened it.

I own a ps3 and have never owned an Xbox but for some reason gamestop decided I needed the 360 version.

Out of spite I kept the 360 version, just because I overheard one of the employees say something about regretting not buying this collectors edition.

I'm finally ready to move on but have no idea how to go about selling this. Ive been tempted to open it so many times, but just couldn't do it. I tried checking eBay for price but it ranges from cheap to 300+ US dollars. I tried Craigslist once but some guy wanted to pay me with a check. I have no idea what I'm doing.

Anyway, my question is, does anyone know the real value of this, and what would be the best way to sell it/ trade it?
