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?

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.

What about if you have to do a refund? That is what I'm thinking.

Win, Loose or Draw, the house always gets it's cut, ay....

I've NEVER had a problem at AGon when doing business through them..

I've only bought... Soon enough, we'll see on the selling..

What necessity?
The only thing I can think of is you SHOULD get a free PayPal MC. 2% back on everything. You can't get scammed on a credit card anyway The banks eat it.
Never an issue selling with a CC on file. Getting paid is a different thing. Agon wants a payment option for fees, either upfront or post sale, but either way there is a listing fee when listing that has to be paid upfront. Having said that, I’m pretty sure you can use PayPal for fees as well, but don’t quote me. 
Thats I think where I was confused about my fees selling on Audiogon.

Audiogon charges fees either upfront or post sale yet you have to pay a fee upfront for the listing.  
I guess your real choice is pay up front then pay up front again or pay up front and then pay again post sale.

Surprised there isn’t a charge somewhere in the middle
