A little bit unfair i'd rather say, as i just read your PM an hour ago while at work and didn't have the time to answer immediately. Anyway, even if i feel a little bit disappointed by your reaction to sell without taking into consideration my interest, i would suggest that you reread the rules and specifically the following two:
"Queue order:
You must follow the order of declared interest in the thread when selling. If a buyer withdraws interest, you should proceed to the member who has declared interest next-in-line in your thread.
Acceptable response times:
You should give any interested party a reasonable opportunity to respond. AmiBay users are worldwide and span many timezones. If you have not heard from a buyer within a reasonable time, you may move on to the next-in-line. We require that you give a minimum of 24 hours between messages, however we recommend you use the AmiBay Trading Process as a guideline."
