[quote name='mask.air.raid']I would say GameStop once a promo goes into effect for it, but you do have the PSN games, so maybe Craigslist may be good, but be careful. Make a new e-mail address to allow specific contact for your sale.[/QUOTE]
Not really necessary. Craigslist utilizes an address masking system that retains anonymity even through standard e-mail client response.
@OP, your best bet is either craigslist, or a good trade-in program for somewhere like Amazon or Gamestop.
