Selling on Audiogon
Any members here sell their equipment using PayPal? I'm trying to sell for the first time (instead of buying) and being told I need a "Merchant I.D. # ". PayPal tells me they don't issue those to non-business's, yet Audiogon says you have to have one to use PayPal for selling. I'm at a loss here. Anyone care to enlighten me?
