I would like to see the sub-categories 'Used' and 'Unused' removed and replaced by a radio button on the Selling Form with at least the following conditions selectable:-

Mint never hinged
Mint hinged
Cancelled to order
Very fine used
Fine used
Used

The Stamp Condition should be displayed as part of the description.

Along with this we would need a filter on Stamp Condition.

The big advantage here is there would be far less maintenance needed for including Used and Unused as sub-categories. Also, these sub-categories are currently not available for all countries, which is a huge anomaly.

As a programmer I believe this would be reasonably simple to implement.

I also think that filtering on Stamp Condition to this level (ebay only provides new and used) will be a big advantage over all of the alternate auction sites.
