I sell cupcakes by the dozen. Unfortunately I am not able to make orders in smaller increments as it is not cost effective for me to do so.
I will do mixed flavor orders however, my rule is one flavor per dozen. So if you were to order 1 dozen cupcakes and you wanted half chocolate and half vanilla, I would not be able to meet your request. If you ordered 24 cupcakes and you wanted 1 dozen chocolate and 1 dozen vanilla, that would be perfectly fine.
