Can I configure a promotion where A and B are mandatory, but the customer can choose any 2 products from a group of eligible products?

For example:

A + B + 2×(C OR D OR E) → GWP

Yes.

This scenario uses the same configuration as A + B + 2×C → GWP, with one small difference: instead of associating the quantity requirement of 2 with one specific SKU, associate it with a group of alternative SKUs.

Your Promotion Rule should therefore contain:

The resulting logic is:

A AND B AND 2×(C OR D OR E) → GWP

The customer can therefore satisfy the final requirement with any combination of eligible products from the group.

For example:

How do I configure the C OR D OR E condition?

In the third Discounted Products row:

1. Set the required quantity to 2.
2. Click Edit.
3. Add C, D and E as eligible products within the same Included Products condition.
4. Save the product selection.
5. Save/apply the Promotion Rule.

The third condition should effectively read:

2 Products with ID = C OR D OR E

Do not create three separate quantity requirements for C, D and E. They belong to the same alternative product group.
