Meanwhile you have only seven days after cleared payment to ship, or you lose your Seller Protections.
You cannot print a shipping label because Paypal is being difficult.
DO NOT SHIP WITHOUT A CONFIRMED PAYMENT IN YOUR PAYPAL ACCOUNT!
No other notification of payment should be considered as anything but an indication you should look at your PP account.
Take a deep breath. We can walk you through this.
Start with the buyer's address.
