Having just left a career at Amazon that spanned nearly 5 years, I can say with experience that it is not so uncommon to find this happening. I worked at a subsidiary, and we had to bill Amazon Corporate for our own AWS use. Being a media-oriented company, this particular subsidiary is sometimes a bit of an expensive AWS customer. As a result, my former department, to this day, uses a Hightail (formerly, YouSendIt) dropbox as its only means by which customers can deliver files to the support and quality assurance teams.
