@CALNNC posted:Here is a case in point about things selling on ebay and Greenberg's pricing. I did not want this car, but stumbled upon it up for auction, a Lionel #6368 in blue, with a $16-42 list in 2021 Greenberg's. It sold for $56, and from the 19 bidders on it, looked like a sniper appeared out of no where and got it. There is an identical car in just as good of shape for sale right now with a BIN of $40. So why aren't those fellows who bid that car into the 40 dollar and up range, and lost the auction, not jumping on this one for 40 bucks?
I assume the term 'sniper' refers to someone who bids late in the auction. I have found over the last fifteen years or so bidding on ebay that it is pointless to bid before the end of the auction. I decide what I am willing to pay for the item and then wait till the end of the auction and bid that amount. Sometimes the price has gone higher than I am willing to pay so I pass and move on. It is a very small number of items that do not reappear at a later date.
