Gunbroker is an auction but not really an auction since mostly dealers reside there and keep their minimum bids high. I have sold 2 guns thru them and got more then a trade-in at a local dealer but less then retail price. They are good as someone pointed out for reference prices and that is pretty much about it. My local dealer will match any price on one of these auction sites.. I will pay tax as opposed to the transfer fee and shipping which in some cases can be a wash. At least the gun is in my hands where I can examine it. Lots of people have been burned buying misrepresented guns ..not everyone but a lot of people have.
