Tip #11: Extend your selling season
Satisfy last-minute buyers. Always let people know when they can expect their packages to ship, and use the Get It Fast icon (available at no charge) to advertise that you offer rush shipping. Choose Get It Fast in your shipping options; offer at least one domestic overnight
shipping service, and ship within one business day of receiving cleared payment.
Tip #12: Let your buyers know their package is coming
Once you have shipped your item it is a great idea to send your buyers an email to let them know it is coming, and include the tracking number. If you use the PayPal label printing solution, the tracking number will automatically be uploaded to the buyer’s order details page.
Give Buyers Timely Shipping Status
Today when sellers use the PayPal label printing solution to print their USPS and UPS shipping labels, their shipment information automatically updates in their buyers' Order Details pages, accessible from My eBay. Now other sellers will be able to easily pass along USPS and UPS shipment information to buyers by uploading tracking information either on their My eBay page or in Selling Manager.
If you do not use PayPal Shipping Labels, you can easily pass along USPS and UPS shipment information to buyers by uploading tracking information either on their My eBay page or in Selling Manager.
