I find it mind boggling that you have so much trouble finding WM mozzarella where you live, my local wallyworld carries 4 brands, just about every grocery chain carries several national brands plus one of their own private labels. Deli counters always have a loaf for fresh slicing, and import stores are stocked with all kinds of cheeses. Any store MUST deal with Kraft products, and Kraft is the parent company of Polly-O. I think if you talked to any grocery store manager, they could surely get you some mozzarella, just be persistent (a pain in their ass). I believe that most of the major brands come in a carton of 6 1lb. blocks, you could offer to be it by the carton! Good luck, or you could always start making your own!
