Costco’s hot dog and soda combo has remained at the same price since 1985. If you make your way to a Costco food court, you can pick up this great deal for just $1.50! Over time the cost price of the deal increased, but Costco countered this by opening a factory to make their sausages. This never seemed to affect its popularity, as 151 million hot dog combos were sold in 2020.
