Bill, the combo prices were for one large "southwestern" burrito with potatoes and coffee, or two "sausage" burritos with potatoes and coffee. The "southwestern" was much bigger, so the fact that you could order one of those separately for $2.49, or one of the sausage ones separately for a buck, made sense. But they then effectively priced two of the little ones for 88 cents more than one "Southwestern" if you bought the combo.

Anyhow, I just got an email reply a minute ago:
