For Magic the gathering products there is quite a good list of stuff that is available, but there isn't a store section for accessories like ultra-pro. I know with how fast the stuff moves it can be difficult to keep track of stock for the site (unless it were linked into a central inventory system for your store...) For me I would like to see at least what you have available or what you usually keep in stock. Not sure how much more work this would create for you though..

Just a thought!
