I'm looking to get a few bone-in Boston Butt/Pork Shoulder's for this weekend and was wondering if anyone had any suggestions. Whole foods wants $4/lb for them, Dominicks has them for a third of that but only had 20 lb packages. Was looking for two 6-8 lb'ers. I drive by the wholesale butchers all the time in the warehouse/west loop district, but don't know if I can just walk in there and get something that small. Any help would be greatly appreciated.
