Ok, I figured out the other discount methods but this one is proving difficult.

Our set-up and what we want to achieve:

We have four products (WHITE, BLACK, BLUE, RED) in a category called COLORS.

If a customer buys any one of the products, they should receive 50% OFF any second product from the category COLORS. Basically, Buy 1 Product Get 1 COLOR free.

What is currently happening:

If a customer purchases two different colors, the discount is applied.

However, if they purchase two of the same product, there is no discount. This is where I'm stuck.

Any insight is appreciated.
