Big Y Supermarket sells Grote & Weigel meat and beef franks. I bought Grote & Weigel meat franks at the Big Y in Walpole MA. I found them in the hot dog/bacon area. They were not in the deli area at the Walpole store. There are several Big Y Supermarkets in CT.
Grote & Weigel are available almost anywhere. Both the Stop & Shops I frequent (West Hartford & Newington) have them. As far as Copaco salamis, I believe they went out of business. Someone correct me if I am wrong.
