Interestingly, there have only been 2 other flavors of SpaghettiOs: PizzOs and CheesOs, which appeared in the '80s. But, there have been a number of variations including the currently available SpaghettiOs Meatballs and SpaghettiOs Sliced Franks. Also, some SpaghettiO varieties aren't 'O's at all and come in different shapes.
Cans of SpaghettiOs carry a suggested retail price range from $1.05 to $1.40 depending on the variety.
