In order to make my life more difficult, I don't have a field for price "incrementation." I have skus that contain full price with options. So, when I calculate the price in the cart I do this:
([Price] + ([Option1Inc] - [Price])) * [Quantity]
This correctly increments the options price into the cart but when the item does not have an option, it predictably zero's out the price and only adds the qty into the cart.
My question now is how to do a calculation for those items that don't have options?
