Good evening, I have a rather
Good evening, I have a rather complicated question I fear, so let me explain. I have a base product that is free and has a feature "seat" with the amount of 1 included. The user can add more seats through my UI and exceed this number (it's modelled as an add-on product with the same "seat" feature). When she has made her final decision she can "checkout" and pay the missing seats via buying the required amount of add-on products. The problem is: in the checkout screen I'm off by one, as if the included seat in the base product is not accounted for. What am I missing?
