Under Simple Delivery, this is what happens to unused SD postage labels. Refunds are made to whoever initially buys the postage.
If you selected 'Buyer pays’ when you created the listing, your buyer will automatically be refunded for any Simple Delivery label that isn’t used after 30 days
If you selected ‘Seller pays’ and offered free postage on your listing, you'll need to fill out the Request a refund for Simple Delivery form for the label that wasn’t used. Make sure to send your request within 14 days of your item selling. Also ensure you add the replacement tracking number of the service used, and it shows delivery.
