I've updated my Amazon pages.  Here is the link to the U.S. one, since most readers seem to be from there. The U.S. page also shows blog posts, which the U.K. one doesn't, so it's better. 
I intend doing pages for France and Germany as well, since I've had interest from there.  I'm not sure if I might write them in my own pretty brutal Franglais and pidgin German, just for a laugh. 
It's inconvenient/a right pain to have to do separate pages for each country.   You'd think Amazon would be able to fix that. 
Probably something to do with tax, I imagine.
