Your auto-buy site is a bit messed up.
I paid and the transaction was confirmed some time ago but your buy page still just shows "waiting for payment confirmation"...
I'm prepared to give you the benefit of the doubt and assume the service you're using is simply crap but I want the book or a refund
Edit: It's finally accepted that I paid and has given me the download. Will update with review once I try the method.
Edit: It doesn't work. The instructions state you need to select values that aren't present. When muddling through the set up and eventually getting a successful signup (having to bypass instructions that don't work), eventually getting login details for the email, the URL provided in the guide throws an error saying security questions aren't set up but won't let you set them up.
Refund please.
