I recently read a blog post about an author who screwed up 17, 500 free downloads of her debut novel by publishing to KDP using a .pdf version of her manuscript.
In short, the conversion to a Kindle-friendly version didn’t quite take and she had to scramble big time to salvage the situation, soothing the angry readers who had already downloaded the book and working overtime to make amends by posting an error-free version.
I admire her courage in coming clean about this calamity and admitting that, in restrospect, she should’ve been willing to spend the money to hire an e-book formatter. She was quite clear that she’d paid a price by going cheap, i.e., doing it herself. The post was followed by a (admittedly, small) chorus of support, with one commenter vehemently blaming Amazon for the mixup, while others cited their own troubles uploading their manuscript .pdfs.
