Soliciting opinions on the necessity of credit card info when only selling


I'm a new member and Audiogon was suggested by a highly respected source as the best site for buying/selling high end audio equipment but, being somewhat apprehensive about the necessity of providing credit card information when my only intent is selling as there are just too many scam artists out there.  Opinion, thanx?

Nobody will scam you.How do you expect them to bill you when you sell stuff? Remember ebay and Craigs list are junk.
My understanding is that I would pay Audiogon up front for the ad and there would be no subsequent billing. If I have been ill informed, please correct my understanding.
There are two options when selling: pay Audiogon up front or pay a percentage based on the amount of the sale (they charge your card after the sale).

Also, providing Audiogon with a CC on file cuts down on the amount of scammers trying to register. Some scammers will not sign up if CC is required.
