How to issue a refund across multiple transactions

IMPORTANT: If processing multiple refunds, always refund the full amount for a single transaction before moving on to the next one. This helps us in the case of a dispute with the bank.

For example:

 Charge for bottle 1 = 89.47
 Charge for bottle 2 = 89.47

If you are refunding both charges, minus $9 restocking fee per bottle, the total refund amount is $160.94 (80.47 x 2). The refund should look like this:

 Charge for bottle 1 = 89.47 > Refund amount: 89.47
 Charge for bottle 2 = 89.47 > Refund amount: 71.47

You should never issue multiple partial refunds.
