Online selling etiquette

1st in line gets the first opportunity. Everyone has their own style of purchasing. The first guy could have fully intended to purchase it and wanted to verify. And the 3rd guy could have seen what you had and walked away.

I've been in this situation and just try to be fair. But in selling there is no fair. I got clipped on a car last year and really made me say screw it to anything I purchase now. If it was meant to be then I will end up with it. If not oh well......
