"Cheapest item for free" discount with a zero-price product in the bundle

Some stores have products with price zero as a promotional tool.

In those cases, you may ask yourself how the 'cheapest item for free' applies.

If a 'cheapest item for free' discount is configured and a bundle already contains a free product, since the discount would not modify the final price, no discount will be applied.

In other words, if there is already a free product, no second product will be offered for free.
