I have a choice to make between using a summed pricing attribute that will compute the sum of the value of the different attributes (which implies making assumptions about the incremental value of the price for each value) and using a price attribute with different levels (which implies making a lot of prohibitions because I can not have 2 premium features for a low price). Is there a recommended way to deal with that ? I know prohibitions are not recommended but I am struggling with determining the price of the different attributes then.
