Thanks to (almost) everyone for your helpful replies. I'm sorry about my late reply, I've been avoiding the Arena while I get my head around things. I'm an honest person and I like to believe the same about others, and I'm far too trusting. Will definitely be changing the way I do business in the future.
The reason Paypal want proof of sending/delivery is that if you can prove it was sent and recieved, eBay seller protection often comes into play and eBay/PayPal will cover the amount for you even if the bank decides it was fraudulent and takes the money back off PayPal. It's one of the benefits of selling on eBay.
Thank you, I can prove that it was sent, but not that it was received. Do you know if seller protection covers people outside the US? I think I read somewhere that you need to live in the US to be eligible.
Who is shouting? I didn't realize my caps lock was on. I would be more concerned with the case rather than nit picking on someone who is trying to help.
It is universally accepted that typing with your caps lock on is shouting, and is considered rude, which is why your post was edited. I politely asked you not to shout. I am not sure how that is nit-picking, but I am not interested in entering into a discussion about it with you. If you have nothing helpful to add, please remove yourself from my thread.
I cant add anything extra to the advice you already received (ponylady and OneLeo have great advice) but I'm sorry you're having to deal with this and I hope somehow that things turn out in your favor
Thank you, I appreciate that.
Ponylady & OL - thanks for the information. No I have not received feedback from the buyer for this or any other transaction. I've replied to the paypal case with evidence of shipping, and I've reported the buyer to ebay so they can monitor any patterns in her trading behaviour. I think that's all I can do for now. I'll update you if the outcome is positive, you probably won't hear from me if it's not.
