As long as a swap is not completed or canceled, sellers can issue buyers partial refunds up to the amount that they earned from the sale. Merely click "Issue Partial Refund" from your swap page and enter the amount that you would like to be refunded to the buyer. The amount that you select comes entirely out of your balance (the seller's balance).
From the iOS App, click the three dots at the top right of your swap page, click "Issue Partial Refund" and enter the amount that you would like to be refunded to the buyer.
Please note: If you need to cancel the swap and you haven’t shipped the item yet, please find "Cancel Swap" on the swap page. For more information on how to cancel a swap, read here.
