Anyone who was a qualified buyer, and asked privately, got the answer. Lots of people asked privately. We even put serious buyers in touch with our credit card processing company so they could get additional questions answered directly.
What criteria did you use to determine a "qualified" buyer?
As someone who frequently deals in transactions over the web for large dollar amounts it is not always clear who is qualified and who isn't. Especially if you aren't doing a high volume of transactions so you don't have a pattern established. One recent transaction we handled for someone started off with an insulting offer of $1000 (from a gmail type account in China (qq.com) and ended up at $38,000 USD)
