The number one reason why we do not conduct consignment auctions ... The seller generally as a rule feels just because he owns it it is worth more and the reserve will be close to everday prices that it can be bought for... therfore no need to stand around all day and hope to get it bought...however, if you have nothing else to do that day.
I have found it best for us to conduct absolute sales where the items will sell to the highest bidder regardless. Its just too easy at a consignment auction for a seller to have his brother, cousin, uncle, friend bid on the item... a P.O. doesn't pay a commission!!
