So I have to install chrome/firefox to order the e-books?? 
Or Seamonkey

Very odd, I must admit. I have tried all sorts of things in IE, and none allow me to see Book 2 or the combined offer. I would be inclined to e-mail Mick via the link provided ("Contact author", I think), tell him of your plight, and he can almost certainly raise a Paypal invoice for you on your behalf.
