Price ebooks less stupidly

This is ridiculous! I fancied this book, but when I saw this:

Kindle Edition 9.69
Paperback -- 8.91 

Something rebellious rose up in me: The ebook should be cheaper -there's insignificant costs for production: no costs for paper, printing. I think a fee for the author and for editing services is fine. But. So come on Westminster John Knox Press: price it properly. I reckon a fiver might be reasonable. The US site has it the right way round (though still on the high side).
