Easy to get a frozen enhanced bone in breast. Getting a non-enhanced one? I don't know. Any chance you have a good butcher shop around? You could also check stores like Whole Foods. Around here, there is a Hillers Market. I bet they'd have it. You might also check the clubs (Sams and Costco). If they have it, you might have to ask. If you live in a large town, is there a market? In Detroit, there is Eastern Market where a lot of the food comes in and gets distributed. I've purchased meat from the wholesalers there (bring cash).
