Quoted from joeraptor2003:We still offer B/W designs and as a matter of fact we will be restocking our site with a lot more. That was one of the issues. We wanted to use our license to the fullest extent which we plan on doing. The designs we had up just didn't do that IMO so I decided to pull the them.
Everyone will not have the same tastes either. So it seems having several designs for each game would be better for the customer. Since it is print per order, more designs shouldn't hurt at all.
I think there really has been limited site exposure for your products. I only ran across the website back in early October, I believe it was. I think you will see more sales as more and more people find out your website.
