There is now a dedicated page for eBid sellers on the popular Postcard Traders Website: http://www.postcard.co.uk/ebid.php
It is available as a free service for members of the Postcard Traders Association who are also eBid sellers to have a link to their eBid seller ID and thus promote their store items.
If you are a member, or thinking of becoming a member, then do get yourself on there.
