When I advertise I don't use a buy-it-now. There are no hidden fees. The buyer pays the auction price and the actual shipping fees. They pay their own FFL fees as do I. I over pack, often spending enough on packing materials (bubble wrap, new box, packing tape, etc...) that it eats a little bit of the purchase price up. I don't charge the buyers for my time or for the packing material, only what the USPS will ship it for insured (mandatory - stated in the auction). I'm not there to compete with pawn shops and other large volume dealers. I can and do charge less than they do for a comparable firearm. I have 100% feed back, and that does help. I check feedback before I consider buying from someone and I check feedback on each bidder if I'm selling.
