If I'm having a yard sale, and someone offers me $100 for a chair

As far as eBay and the buyer were concerned, the deal WAS closed at
the published end of the auction.

Being forced to sell a plane below market value doesn't sound 'fair'
to me.

The seller set the value of the plane in the Reserve Price.

One should not play the game if he does not understand the rules.
