Having published a trilogy I thought of offering the 1st installment for free for an extended period of time. In Mark Coker's marketing book I found a few websites that dedicate themselves to free ebooks. Upon visiting http://freebooks.ontheknob.com/blog I found a disturbing post saying: This site has been closed down to comply with Amazon’s new policy: no free books may be mentioned by an Amazon Associate or they risk losing all income for that month and possibly forever. In fact, even if the site never mentions a free book, they can lose their entire month’s income if the people they refer to Amazon buy “too many” free books in a month. Does anybody have experience with this new policy of Amazon, which went into effect March this year?
