I have run into a new problem, maybe I never implemented your solution properly. Basically, if I have one of those products with the charge amount we discussed and another normal item in the cart at the same time things don't really work... I need the checkout to work if I have the charge rule for the multiple items with one price and if I have a normal item that may have discounts,etc. added to it... Is this possible? Or do I have to encourage my client to get payments pro?
