Typically the standard acceptable timeframe for sending payment is (3) business days. The goal for everyone is a smooth and successful transaction. So, if three business days have passed and you have not heard from the winner, try contacting him or her to see what's what. You can send a payment request through paypal or contact them through the forum or SoapSaver site. If you still cannot get in touch with the buyer, it is reasonable to relist the item if you wish and leave a negative rating and comment for the buyer.
