I have not yet figured out the reason for reserve on gun auctions. Maybe it should be obvious but not to me. The beginning or minimum bid on a gun today on Gunbroker was $200. So, I bid slightly over that amount and got a robo-message that my bid was high bid but did not meet the reserve. I bid $250 and got the same and when I got the same with a $275 bid I stopped as I did not want to pay more than that for the gun...at least not right now. So, the reserve has not been met and the bid is at $275. Why doesn't the seller simply move the minimum bid to what he/she wants minimum? So, will someone explain? Thank you.
