People do order then not pay on there. It's quite easy to do that. It can be done on an auction because a buyer might make what is the winning bid quite a while before it ends but if something is a buy it now order they have to click to buy it then so I don't get why they don't just proceed on and pay for it. Some people click buy it now then leave it for days before they pay or don't pay at all. So unfair on the seller.

Thanks for the warning, Margaret.
