While I have been an Audiogon member for many years and only made one purchase (maybe a decade ago) I'm a little confused on how one pays for an item on that website. I'm trying to purchase an amp from a long term highly rated seller. But he's asking me to do some odd things; first he wanted me to send payment using PayPal's Friends & Family method. I did not feel comfortable with that (we're talking over $4K) so asked to do a CC and now he wants me to send him a copy of my CC (front and back) plus a copy of my license. Is this typical? Doesn't the site allow you to make CC purchase like ebay without sharing all that info with the seller?
