If you're using CloudFront and pushing over 1000 TB/month from the US and EU edge locations, the marginal price was cut by 40%.<p>... which I find rather annoying, really.  Every time AWS prices are cut, it's the largest users who get the largest price cuts.  What happened to the idea of "we can get good rates by buying in bulk, and then pass those rates on to all of our customers no matter how small they are" which AWS launched with?
