Thank you for your post. I understand your trepidation, and you're right to be skeptical. If a person is asking you to ship something heavy to another country with no questions asked, they may potentially be planning to send you a fake email confirmation of payment.
As mentioned by @Sidney08, please check your actual payment history to confirm receipt of the payment before you ship, and make sure that you ship with tracking. Do not let the buyer arrange a pickup with an agent, as that would void your Seller Protection.
I hope this helps!
