The worst aspect of AWS is that once you get to a certain size, you can negotiate bulk agreements, especially for things like bandwidth. At a previous job, we cut our bill down by quite a bit this way, but it was annoying to have to schmooze with sales people.
Great you're pointing it out, as this is also something a lot of organisations are entirely unaware of in my experience.
If you're paying more than a few hundred k/year (worth starting to try below that; success rates will vary greatly) and are still paying the list prices, you might as well set fire to money.
