I am in the UK and have sold an item to someone in the US. She wants me to invoice her through PayPal for the book and tracked & signed for, rather than use the GSP option. How do I do this, if indeed I can.
If the sale has gone through using the GSP system then the only way that I can think of is to cancel the sale and relist as a Buy it Now and tell the buyer to buy it again.
GSP may not be a good option for books. If coming into UK they are free of duty and VAT.
I have never heard of sending a Paypal invoice if you are selling on ebay - that suggests an off ebay sale
