If you are going to go to GC, go early in the morning on Sunday or Monday. No one is there, and especially on Sunday they should have a large crew. Ask to talk to an Assisstant Manager, they have been at GC for the longest.
Also, talk the price down. Ask for small consessions, like a free strap or cable, or whatever. You can end up saving quite a bit, but the guy on the other side of the counter still ends up with a good sale.
My favorite combo to sell:
Yamaha RBX100, Fender Bassman 25 watt, gig bag, stand, strap, 21 foot monster cable and a set of D'addario strings.
Full price is $515. I would sell it at $430, and the customer always went home happy, and with good gear.
In case you didn't know, I worked for GC for a year and a half. Just quit recently to go back to school (I'm in my 3D drafting class, being bored by intro lectures)
Rock on
