* NBS has option if a Transaction is Sale or Refund
* Refunds come in as postive amounts/quantities.
* When Transaction Type = Refund, we need to multiple the quantity by -1
** Note it may be possible for a Refund to have coupons that are already negative, which would be correct to make them positive.
