A friend of ours found a new website recently that is sort of unique. It is 100's of artist and merchants coming together in one place. I guess, a little like Amazon. Their name is CafePress. They claim to have 38, 800 Gordon Setter products. I browsed over a dozen pages and found lots of things that I don't see in other places. If you go to their website, you can learn more about them and the people who make up the site.
I have not yet ordered anything from them, and can't tell you their customer service policies, but I can tell you they have lots of Gordon Setter products and gifts to choose from.
