I wish I did - I just usually try to sell a variety of items & offer combined shipping so they will look at my other stuff, sometimes it works, sometimes not. I just know sometimes I am looking for one item but can be swayed if a seller has another item i'm interested in - I am curious to see if others have suggestions.

Maybe you could just join some other message boards and promote your listings there too. I noticed a few people did that on FH (all they ever posted was their ebay listings).
Try: styleceo.com (They have/had an ebay section - board isn't great but they have a few people that check it out)
myvirtualcloset.com was supposed to add an ebay section plus you can post your pics there and say you are selling them if nothing else.
