I'm heading to my local GameStop tomorrow and they had a copy of Eternal darkness last time I was there. I'll look to see if it's still in stock and I'll send you a PM to see if you want it
Sorry, they didn't have Eternal Darkness at the store nearest me but there are four other stores near me that have it for $14.99. Let me know if you want me to pick it up for you since I plan to go to the one of them that has it next weekend
There's a deal towards the end of the sale that says buy 2 get 2 free on preowned games. I can look to see if there are still any copies of Eternal Darkness then and the price would be cut in half
