SPI in Toledo, Ohio is the closest I can find and they have to order it. It would be $61 per 6 sheets of 2" plus tax and freight. Seems a little high.

Can someone recommend a different source or substitute?

Try here.

Roxul AFB's are available in 3" batts for only $19.78 at Great Lakes Gypsum Supply in Lansing, Michigan. They are in stock, and you can pick it up right there. One of the worst neighborhoods in town though.
