Edit: The price has returned to normal now.
My attempts to put Two Go to Italy in the Kindle Matchbook system have failed miserably! I didn’t realise this scheme only works in the USA and not in Europe.
As I had promised purchasers of the paperback they could get the eBook free I’ve reduced instead the price of the eBook to £1.99 which is the lowest the system will allow me to set it. Not a huge discount of course but it’s the best I can do. I will put the price back up to £2.99 in a week or so.
