Welcome to eBid.
Maybe one of the reasons you are not selling is because, for example, you are asking for GBP 125.00 for the Japanese Laser Disc here on eBid and you are asking for GBP 110 for the same Disc on Ebay.
People do check sites for comparison.
I would have thought that you would ask a lot less here considering there are low to no fees involved. Some buyers are pretty clued up about MaO as well.
