good call, thanks for the link. they said it was from documents I had sent to the kindle. looking at instapaper I apparently did have something small sent on the 8th and I guess I was charged for a bunch of stuff all at once or something. Amazon's interface makes no sense, it has a thing for "order date April 16" that says I was charged $4.05. when I expand April 16 it has a bunch of instapaper charges up to October 6th for $0.15 each. so why does it say April 16? I guess there must have been more charges since then that they don't show me yet that they are billing to me at some arbitrary time and which they will show me attached to some arbitrary date. oh well, at least their customer service is good.
