I'm confused, where are you seeing $160 for shenmue? That usually goes for around $30 complete on ebay. Idk if you're in the states but craigslist is great but there aren't always deals, alot of time youll have to wait a month or two for decent stuff you're looking for. Just this week though I picked up a second DC i intend to sell, 2 controllers, VMU, Power Stone, THPS, Toy Commander, NBA 2K, NFL 2K, Trick Style, Crazy Taxi and PenPen Something-or-other all complete with case and manual, for $50. Plus some demo discs.
Craiglist you find lazy people who don't like ebay and don't bother appraising what they figure is their old junk, otherwise I'm sure this guy would have realized Power Stone alone is worth $50 easily.
Couple years ago I got a CIB ps1 with FF7, FF9 and FF Tatcics all mint black label for $30. Guy was moving out of state the next day and just wanted it gone.
Best deals I've ever found have been on craigslist where people have been selling the whole console with games for cheaper than just the games are worth. I just resell the console after if I already have it and that's just more money of what you payed.
I'll end up paying like $20 for all those games I got plus a controller once I sell the DC they came with
Also forgot about a couple months ago when I got shenmue, sonic adventure and soul calibur for $40. He also threw in crazy taxi without a case just cause he had no use for it. disc 1 for shenmue unfortunately didn't work but I met up with the guy again and got $15 back so paid $25 for the 3 games I got.
