OK I don't edit shopping either, so take this with a large bag of salt. Comparing you and my dog murpy sites I can see shirts for sale on his site , not on yours. If you design and sell your own shirts, your site should be listable, but I can't see any indication of that. They might be there, I just can't tell as everything I see is just a page of links, and they have other merchants/companies? names. I think I see your business model, but shopping listings (I pretty sure) require information on unique products as well as the ability to order online. If you have your own range make them a feature and that should help. Disclaimer - re read the first sentence.
