You can buy individual blocks and/or bags of Grande from Vinny's Italian Grill and Pizzaria
. Corporate policy is that they sell every ingredient they use, be it cheese (Grande), flour (All Trumps), tomatoes (Escalon and stanislaus), spices, pastas, OO, marinated artichokes, balsamic, etc
). I buy individual 7 lb. blocks of whole and part skim mozz for $19.26, including tax ($2.75/lb.). If you ask nicely, they'll sell by the lb. for a few cents more/lb.
I've since found out from the manager of the Hillsborough restaurant that his brother and sister-in-law own a mom-and-pop Italian restaurant in Durham (which happens to be my favorite Italian restaurant), and that they'll sell Grande, All Trumps, and 6-in-1 to customers if you ask.
