Fix price if X amount of products from category Y is in cart

Hello,

Consider that we have a category call “New members” and this category has 20 products.

We want each product to have a fixed price of 20 but only if the following condition is true:

– 3 or more products from the category “New members” needs to be in the cart in order for the discount to be applied, but it should never be applied for more than 3 items. So let’s say they have a standard price of 100 and the customer adds 5 different products in cart they should be priced as

20
20
20
100
100

Would this plugin be able to handle this? As we might have 100 products where this rule needs to be applied we can’t add all the conditions based on products but rather on product category.
