I have had very good luck selling to, and buying from, Guitar Center despite the fact that the closet=st one to me is about 100 miles away.
They'll ship from any GC to my house, and they don't use shipping as a stealth profit center.
I've also traded in thousands of dollars' worth of stuff with them at several of their stores, and gotten a good deal on my stuff plus a discount when I applied it to purchasing stuff in that store.
I've bought three used Kurzweils from them, one of which was defective on arrival -- and GC paid to have it shipped and fixed.
