Hello,
I attempted to buy the PDF of Pathfinder: Unchained when it was released this morning, but I the website said my card was declined. I live in the UK so I am not sure if that has anything to do with it.
One thing of note possibly is that I later went to check my online banking with my bank and while checking pending transactions I noticed that each time I had attempted to purchase (5, frustration slightly plays a part), it is logged as pending. I would have thought that this would mean that the payment was not declined.
I hope I can get some help on this because I would quite like this book :).
