My initial enquiry was to obtain ONLY an estimate of how much my plate would be likely to sell for, not to actually LIST it with the company. Had I realised it would be ADDED instantaneously (without my prior knowledge or consent), I wouldnt have made the enquiry.
Perhaps a caveat should be placed in capital/bold lettering (unless I missed it), on the site, stating that this is the procedure so as to avoid any misunderstandings in the future..... just my opinion.
