Paypal shipping is easy. If a buyer pays you through Paypal, there should be a button next to the transaction in your Paypal account history that says "Print Shipping Label". You can pick which shipping method you want to use, either USPS or UPS. From there you decide if you want to send something Priority, First Class, etc. (or through UPS: Ground, 2nd Day Air, etc.) Fill in the package weight, choose any extras like insurance, verify the addresses, and hit Print. The funds come directly out of your Paypal account. And you can even choose to have the packages picked up at your house, so you don't have to drive to the post office if you don't want to.
