Well, Colonel, here's a tale to do with prices and values that might restore one's faith in people's fairness.
I had an item on sale on Ebay - under their 'sell for a £1' offer - which I started at £1,000.
In the last moments, the bidding jumped in £20 and £50 increments to about £1,250, then leapt in one go to £2,250 right at the end.
Just when I was rubbing my hands with glee, the message came from the frantic top bidder, saying he had accidentally omitted the decimal point in his last bid (which I assume should have been £1,300, but came out as £130,000) winning at a price beyond his means. It was obviously a genuine mistake, and he was so apologetic, that we agreed to cancel the auction.
I looked at the bidding history, then got in touch with the underbidder, to explain the situation and ask if he were still interested - in which case I would offer the item to him at a price of £1,300, since it would not be fair to expect him to go up to his maximum. He advised that he WOULD like the item, but would pay £1,500 as he thought that was more reasonable. I was grateful for this, but even more so when he called to collect the item, saying that as he had been prepared to go to £2,200, and that as I had been more than fair in my offer to him, he was actually paying me £2,000 !! (He added that if I had attempted to get the full £2,200, he would not have bought the item!)
Perhaps the moral of this story is that if you treat people fairly, they will do the same for you!
PS - Just to confirm that E-bay did not miss out on their 10% in this case.
