please ignore the part in the title that says Kindle reduced % wise as that bit i got wrong but Kindle books ARE included again.( https://affiliate-program.amazon.com/kindle so looks like it's classed as a normal product and also the kindle its-self is as well. The Operating Agreement was updated 1st May to include kindle books as digital products, also kindle books has now been removed from the list of excluded products. for other details of changes see https://affiliate-program.amazon.com/gp/associates/help/operating/compare
Ha, finally! Now where did I register my ebook domains again... (thanks for the update, it's great news!)
It always worries me when Amazon change products commission rates... I remember when they took the Nintendo Wii completely off, meaning you couldn't earn a penny for referring it. I had promoted it for ages and overnight I went from earning $$$ to 0!
Saw that, this is good news. Kindle eBooks robbed me of some $$$ last month. I did well promoting a new book, but 1/3 of the sales were for the Kindle! But I take that as a good sign that people are very interested in eBooks.
