Hi Patrick,
I see you live in the Twin Cities area, if you want bone in, talk to the butcher at Cub Foods (or wherever you buy your groceries). They often have them in back and use them to cut up country style ribs or perhaps grind into pork sausage. I've found they are more than happy to order them in as well in the event they are out at the time. If you plan a few days ahead, there is usually no problem getting these types of butts.
Good luck!
