I want to create a campaign in which the customer must buy a product from one category, one from another category and another from another category (one product each from 3 different categories) and all this at a fixed price, e.g. $90, how do I do that?
ex.
category t-shirt - 1 product (100$)
category pants - 1 product (300$)
category parfumes - 1 product (200$)
total: 90 $
and the discount should be activated only when there is a product from each category, not when there are two products from the pants category, for example, and one from another category, not only when there are 3 products from different categories
any sugestion ?
