Refunding an order must be done in PayPal or Stripe

To refund an order paid for with Credit Card, please see this help doc.
After you've refunded the order, it will appear in the "Refunded" section of your Sales section. To view the order, either paste the order number into the search box at the top right hand corner of your sales section, or select "Refunded" from the dropdown menu, and then scan for the order.
Important Note: When an order is refunded, Limited Run does not change the inventory of the ordered products. This is because the reason for refunding the order is unknown. It could be damage, lost during shipping, customer doesn't want the items, etc. So you must update the inventory on your own.
