WHERE can I find Duff's Hot Roll mix?!?!?

We used it to make part of our Christmas breakfast growing up, and we always had a hard time finding it, but would find it in our small town local chain, Food Lion. I have no idea where to find it nowadays, and I want to make that breakfast soon, if not by Christmas preferably! I can't find the mix online, I'm wondering if its a foreign mix (I'm in Virginia, which is where we always found it growing up) or maybe needed from a specialty grocery store??
