I was just at a LSS today and they had a few of them in stock. They have a online store but I haven't ordered from them before so I am not sure about their customer service. It is based out of AZ called
www.themadscrappers.com. I only looked to see where the store was located at and saw that they had an online store. The boxes are under catagory>altered projects>Misc. chipboard> and are about half way down the page. HTH! Good Luck finding them.
