The GC here gives you 50% trade based on what they think they can sell the gear for. So if they're gonna put your used guitar up at $250, they'll give you $125 in trade.
Sucks but I've done it - selling on CL can be a real PITA. Responding to "I'll give $200 for that guitar you have listed at $500" emails for weeks gets old real quick. I'll trade it in at GC before I give some CL low-baller lol!
