OT [very] Guitar Sale

I know there are quite a few musicians using this group and hope that 
the others will forgive the OT posting. My son has an Epiphone sitting 
in it's case which has hardly been used. He mainly these days uses his 
acoustic but now wants a Fender. So he wants to sell the Epiphone to 
fund the Fender. Is there a good way to do this or should we resort to
ebay.
I'm happy to take this to email if necessary.
