Payment for eBooks is made by PayPal via the Payhip website (because they deal with the dreaded VAT calculations for me).
You'll receive download links via both Payhip and BookFunnel, so you can either side load to your device or have BookFunnel load the file for you.

Postage is super expensive from the UK, so I don't sell signed paperbacks as a rule, but if you really want one, please contact me via the contact form.
Cost will be the retail price of the book(s) plus P&P. I'm afraid P&P will be at least £10 in the UK and £20 overseas, possibly more depending on the book(s). I only send tracked/signed for so the packages are insured.
