I have just lost a sale because the potential purchaser pulled out saying he thought I was not genuine. He asked for my telephone number, but I wouldn't give it to him because I'm ex-directory and don't want people I don't know having it. I forwarded my bank details to allow him to do a bank transfer.

It raises an interesting point - how DO you prove you're a genuine seller ? I know I am as honest as the day is long but how do I prove that to other people? I have sold items on OM before without a problem so there are people who could vouch for me I suppose.

Any other ideas ?
