I really like Amazon's S3 and similar, I just wish Amazon allowed me to set a cap on my account.
I'm aware of billing alerts, and they're quite useful. But I am really paranoid one of my properties is going to get linked to on Reddit, Digg, or similar and then I'll wake up to a $5K bill which I can ill afford.
My original, unedited post title (grumble grumble) sort of covered that- I served content to 100k users, but it cost me less than a dollar. S3 is amazingly cheap.
Not going to disagree (because, really, it isn't worth it) but I thought my original title brought a little more emphasis to how cheap S3 is- as the OP demonstrated, I'm not sure that's so widely known.
