I would like the possibility of giving the customer a "Credit on shop" coupon of a value greater than the price of the product to return ("Refund money"), in order to not losing liquidity with returns. For example:

Customer buys and returns a €40 product. In the returns portal you can choose two options:

1 - Money back (€40)

2 - Store credit (€45)

You could choose for an extra percentage of the product price or for a certain value in €.
