It just wasn't selling. I can arrange a bulk order for you if you'd like, or if you can get a few more people to request (say, 5?) then I'll see what I can do to get it back in stock!
We'll probably bring it back eventually either way, but right now we're stocking up on so many new items for the new website we're having to cut back on things that just aren't as successful. When the financial stresses die down a bit, we'll be more prone to stock some of the slow-going products again
