Not the guy but you can just buy your ebooks from someplace else and use calibre to convert/send them to your kindle.

Im kinda cheeky and use Amazons Send-to-Kindle service to send ebooks in epub format to my kindle via wifi

I do this as well and leave the site name in the filename where it was downloaded from if it was part of the filename originally.
