I want to sell an Xbox code on eBay, if I send it through the post will I be protected?

If I sell the code as a physical item through the post can the buyer then turn around and say the code doesn't work and demand a refund?

How do I protect myself against that?

That depends on 'many' factors all listed in Paypals seller protection policy for you to read and then you can risk assess your own transactions.
