I use to buy/sell on Audiogon years ago but much has changed. For one, it irritates me that they don't allow you to accept payment except through Paypal -- not by cashier check which they use to. Okay but the major issue, when I try to set up Paypal method, it tells me they return error that Paypal cannot verify me, although I did get everything set up and linked to my bank in Paypal. So now (since they don't seem to have a phone # ) I have submitted a problem report to them.
If they don't resolve this in a timely manner I guess I'll have to do my selling through Ebay.
