Initially, Amazon’swould push converted files to your Kindle for a flat $0.10 each. Well, changes are afoot: Amazon has announced expanded format support, but a higher fee of $0.15—at least.
The way things used to work, a single dime would grant you a Whispernet delivery of anything from a simple JPEG photo to a 120-page manuscript of your Xena: Warrior Princess fanfic novella. Now, Amazon has introduced a progressive payment scale, based on the size of the converted document. It’s pretty simple: $0.15 for every megabyte transferred over Whispernet, rounded to the next whole megabyte. In effect, this means that the minimum transfer charge is $0.15, and that larger documents—but still the kind that people regularly transfer to their Kindles, could cost upwards of 50 cents. In other words, you’ll be paying a minimum of 50% more than you used to.
It’s still free of charge if you transfer the documents over via USB, and sending them to “name”@free.kindle.com will return converted files to your email address gratis.
