I went to the New England Guitar Expo last weekend near Hartford CT to sell a few guitars.
Sold all 3 in about 10 minutes. No dickering. One guy tried. I just turned and sold it to the next guy! I don't negotiate.
Sold a Squier '51 Precision, a 2008 PRS SE-1, and an Epiphone "Inspired by Gibson" Les Paul. Real nice guitar.
I buy gear over several months and then sell it for a profit. Love doin' a little pickin' on craigslist and fb market place. You can still find the occasional great deal!
