I need to be able to allow multiple free items from a variable product. I tried to play with the options but I can only add multiple items from one variant.
Example
1. Buy 2x of Product A and get 1x Product C (variant 1) and 1x Product C (Variant 2)
2. Buy 1x of Prodct A and 1x of Product B and get 1x Product C (variant 1) and 1x Product C (Variant 2)
