AND operation in filter and creating BOGO with different product of choice.

Could you please explain how to apply the offer only to a category of the brand. Lets say, Brand = ABC and Category = mugs –> buy one get another product (cheaper or equal to the current product) free.

I tried the free product rule but it adds the same product twice, can it be buy one and get any product from the category free (end price being the price of the expensive one)

How to implement this logic?
