Everybody pays the same premium. What high premiums does to me is depress the final bids if you have a working brain. If the gun is worth 3,000 to me and it cost 25% to bid I just lower my max bid so the total is 3,000 or less. If I can't get the gun for my price I don't care to over pay just as you don't care to over pay. The seller looses because more bidders drop out before the feeding frenzy starts.
