hi I have configured a BuyX GetY voucher and it works but I am noticing that having selected a manufacturer in Y the system always adds me the same product as a gift but if this is not available by mistake instead of adding a second product from the same manufacturer.
Even setting Y with the list of products, entering the coupon code always inserts me the first and if not available because it is out of stock instead of passing to the second by mistake.
How can i solve it?
Thanks
