Gamestop during the tiered promo. I got about $150 from most gamecube and ps2 games so I was pleased at what I got. As cheap as GS could be, I half-expected to get no more than $75 but it doubled, I was delighted.
Amazon. That $75 console credit was AMAZING and I basically got rid of a stack of games I wasn't playing and got a 360 and PSP for less than $100 total.
I think it's kind of a shame that neither Best Buy or Toys R Us trade in programs are not listed. The money they offer for used game titles is very competitive, and I think that either of them are better than what's listed here.
I have to go with Gamestop on this one due to the tiered trade-in promo awhile back. If it wasn't for that, then I wouldn't have gotten a PS3 for $50 out of pocket.
I don't think Goozex would apply because you aren't trading into a company, but more of trading with other users which is why it is listed in the Game Trading category.
I know amazon and gamestaq had better values... but I personally used Gamestop's trade programs to get myself a PS3 very cheap... so... gonna go with Gamestop
Gamestop unfortunately gets my vote. It's still very conveniance factor is still important to me. Hopefully someone else really steps up this year so I never have to go to one ever again.
