"I purchased a used copy of "Middle-earth: Shadow of Mordor" for PS4. Since I was in middle of another game, I didn't get around to testing the disk. A couple months past and it was time to try the game. To my dismay, the disk was damaged and the PS4 would quit the game. I contacted GameFly for an exchange and they "don't offer 1 for 1 exchanges". Since it was past the 30 days, they couldn't do anything for me. You'd figure a big company like this would have something for me. Maybe a $5 voucher to make me feel better? You'd also expect that they would test the disk before reselling it. Their email responses back to me were borderline rude and very unhelpful. It was only $17 after shipping so I'll take it as a life lesson but wow, not impressed with GameFly. It's not the money, it's just the principle. My recommendation... just avoid buying used games from them. It's not worth the risk of being part way through a game, the game console being unable to read the disk, and then being out $30 or whatever you payed for it."
