If you have an account already. Just bring up paypal.com/shipnow it will ask you to log in and it brings up the blank form to fill in where you are sending it to, it ask what type of shipping you want, date you are sending it , next page you check all the information, then press continue/pay - and it subtracts the amount it showed you from your pay pal account. It is pretty easy.
You are welcome. Glad I could help out a fellow Listian. Then when you pay a pop up window pops up, select print and your label for your package prints out of your printer. Post office just has to scan it in and accept it.
