Hi Sports Guy,
There are lots of articles here at SUn to help you grow your ebay business. Here is one to get started: http://www.startupnation.com/pages/webinars/OS_How-to-Start- an-Ebay-Business.asp
I don`t sell much on e-bay at all... but I am a bit obsessed with shopping at a certain E-bay store (Ibaze). I know I used to shop there for new clothes about once a month.
Part of how I found them was searching for very cheap corsets, and an auction with a low intro price attracted me to their store. I noticed your store does not have any auctions at all, only Buy-it nows. Perhaps lower priced intro auctions would help you show up more in searches.
I am not in your target market though so I would take my considerations with a grain of salt.
With your website, setting up the domain to forward to your E-bay store couldn`t hurt, and then you could use a .com URL on your business cards/promo cards.
