How much is three foot sub?

That should be $18

Well my opinion on that is there's no such thing as a 3 ft Sub which is also a fact. Bottom line it only goes up to a foot long based on the last time I visited Subway for example? So you would literally have to purchase three of them things which you would end up with six of them because they always would cut them in half. Nonetheless a foot long itself costs like $5-6 and some change depending on which sandwiches you want? So when you take the time to multiply the total of one by 3 you would come to a total between $15-18 and some change plus tax making it about $20 for all three sandwiches

Right
