Because this purchase will not be eligible for the PayPal Buyer Protection program (which I believe is currently only available on eBay), you may want to ensure that you are sending the money to a Verified PayPal account. However, as this is a non-US account, be aware that the account holder would probably need to complete the Expanded Use process in order to become Verified, and that may cause some delay. You may also need to be Verified in order to complete the payment if it exceeds your Sending Limit.
