I had an auction of Grand Theft Auto III, Vice City & San Andreas for PS2 up and got pulled. Couple of people emailed me about it but only want San Andreas. I told some guy I wanted $50 for all 3 he said it was OK, now he only wants San Andreas. I don't want to over charge him or sell it too cheap. What's a good selling price? The game comes with the original cover art but no manual. Thanks
