I listed a bunch of boxes of "rarish" French ammo on Gunbroker that belonged to a friend. I trusted that the details that my friend supplied to me were accurate including the fact that he said he checked and found that there were 20 rounds per box for a total of XXX number of rounds. And he wanted to receive a specific price for the ammo based on his actual cost for it.
After someone bid on and won it, I picked up the ammo to ship it only to discover that there were only 15 rounds per box instead of 20 rounds which increased the price per round by 25% since there were 25% less rounds.
So I sent a detailed explanation of "my mistake" to the buyer and gave him the option to either buy the ammo at the higher price per round (the amount of his bid) or that I would cancel the entire sale, hopefully through Gunbroker.
The buyer was an experienced ammo dealer who was really understanding about it and bought the lesser amount of ammo for the original price that he bid.
I couldn't very well manufacture any more of the ammo to supply the number of rounds advertised and I wasn't about to pay for my friend's misinformation. Mistakes are made because of human error, and this honest mistake was able to be ironed out with the right amount of communication. A new deal needed to be made through a meeting of the minds. There really is no deal unless there is a voluntary meeting of the minds with all of the terms being known and agreed upon.
