Help needed from readers.

As a writer it's hard to know what does or doesn't work where trying to promote books is concerned, and so I would really appreciate it if anyone who has bought one of my books could let me know where they heard about it and what made them decide to purchase a copy. If you don't want to post on a blog, please email me as I'm really interested in knowing what works and what doesn't where promotion is concerned. Thanks in advance.
