One of the most important elements was that, they didn't want to pay before receiving the items. This didn't make any sense to me as most business expect payment before delivery but we were just people selling stuff. So we setup a web site to reflect the business we were trying to establish to look more professional while still explaining that we are selling our personal items to support our business. A couple weeks later we had to shut down the web site temporarily and remove the personal items form availability. We could not keep up with the mail.
People misread things easily.
We now knew that it was not hard to get people to respond. They respond to businesses. And they respond the the scams that LOOK like legitimate businesses as well. This was a very scary realization. What an awful awakening that was.
