their site is weird. If you click the link you provided and navigate through the eight boxes down the page, those work. If you click on the links on the very top of that page, it takes you to pages that look very different, almost like it's a different storefront. Weird. I was first looking through the links on the top of the page, I think that was the problem. Using the eight boxes down, the code works (but I doubt I'm ordering anything...I don't understand their pricing, some things are marked way up, others down).
