it would be fun to know the break down numbers for sales of The Price Fix Five, or is it Six or Seven by now?
Also would love to be a "bot" the the Amazon Machine to peek as the break outs for each price range starting from $14.99-$15.99 (or higher, wherever the begin pricing ebooks released with the release of the HB version) then down in dollar decrements. Basically what is the real sweet spot for pricing? Then cross reference those numbers over time to watch the pattern emerge.
