What you did is :-

You list a car for sale on eBay.
You want atleast £500 for the car - So you set a reserve of £500.
Someone approaches you to offer below £500 and you make a deal!
The listing ends at below £500, the car goes lesser than you thought.
Afterwards, someone approaches you offering £500 for the car during the sale because of your greediness.
You sell it.
