Returns are always subject to the individual merchant’s policy, which can typically be found on their website or by contacting them directly. If you make a return and the merchant processes a refund, it will automatically be reflected in your Payment Schedule — further details are below.
In general, refunds are applied starting with your final payment and working backwards to earlier payments.
If you have returned an order in its entirety and the full amount of the order is refunded, any upcoming payments will be cancelled and any payments you have already made will be refunded back to the card you paid with.
The same principles apply if you’ve returned a portion of an order and received a partial refund.
