How did you significantly reduce your AWS cost?

This Hacker News thread is full of tips, tricks, and references to reducing Amazon AWS costs.  There is plenty of good advice from cleaning up the data and releasing unused resources, to monitoring the reserved instances usage, to moving data from elastic volumes to the Amazon S3 for cheaper storage and smaller traffic bills.
