2. Split a Venti Frappuccino

A Venti Frappuccino is 24 ounces in size and costs $4 while a Tall Frappuccino is 12 ounces and costs $3. The smartest thing to do here is to order a Venti Frappuccino and ask it to be served in two tall cups. You can now share it with your friend and save $1 each. Quite a smart thing to do.
