A good rule of thumb for sellers is that you should be prepared to ship within three days of any auction's close to ensure arrival within two weeks. Savvy online buyers in today's ecommerce-enabled world are unprepared to wait any longer than two business weeks for an item to arrive, and in most cases buyers begin to get anxious if they wait longer than seven to ten days. So when you receive a payment, contact your trading partner immediately to thank them, and then ship as fast as you can.
