Has anyone tried Black Bear Natural Casing Beef Franks? These are only available at Shop Rite. Best Franks available in this area in my opinion. They also have excellent roast beef. I prefer it to Boar's Head and Thumann's. I know that the company is in Moorestown, which is in South Jersey. Are they a subsidiary of Shop rite? Are these franks only sold at Shop Rite or are they available elsewhere?
