Change Catigories
I have not seen a way to change categories if someone felt they needed to change especially when their listing expired. Let's say you charged x dollars for a 60 day listing and it was an item for sale that sold in 10 days or so, leaving 50 days of paid listing time. What I would like to do is allow them to list another item for the remaining time but it may need to be in another category. By allowing the customer to roll over their remaining time could encourage them to keep re-listing.
