If your listing ended with Get It Now, then payment will already have been made by the buyer. For auctions ending with a high bid, please await payment before continuing with the transaction.
Buyers are allowed 3 days after the listing ends to provide payment. After this, the listing is considered past due, and you have the option of canceling the transaction or messaging the buyer and offering them additional time. Any auction that is still awaiting payment after 30 days will be automatically canceled.
When you cancel a transaction, Points will not be transferred to you and you may relist or keep your items. Non-payment wastes time and energy, and buyers who do not pay will face immediate bidding restrictions and repeat offenses will result in account suspension.
Buyers have different options for payment, but as the seller you will always receive Points.
