Hi All
We now have better documentation describing the process of refunding an order which was paid for using 2 or more different payment types:
The most common occurrence of this kind of thing would be when people have a gift voucher which they want to use but is worth less than the total value of the order, so they then pay the rest on card, cash, etc.
It often causes trouble when it comes to refunding these types of orders, hence the write-up.
