I think those are frozen or refrigerated, I'm pretty sure I've had them before, in smaller boxes, sold at AM/PM MiniMarts in Pittston, maybe even the relocated WalMart. Weren't very good to me, but I'm used to Ghigarelli's (OF) & Sizzle-Pi (Kingston.) They were a little better than Agostino's Bakery on OF/Duryea border, whose half-baked cheese looks "almost curdled."
Nardone's is refrigerated and usually found in the dairy case in supermarkets, Matermark, at least around here. Old Forge pizza also reminds me very much of the original Ellio's frozen rectangles from back in the '70's before McCain bought the brand name out...http://www.pizzamaking.com/forum/index.php/topic,19913.0.html
Nardone's isn't too bad if you have a severe case of the munchies and only bake it long enough to just melt the cheese and not brown it, sort of like those old-time vending machine pizzas. LOL
