Pet peeve in case Jeff Barr (or another AWS person) reads this. I purchased multiple 3-year heavy utilization RIs just a few months before the price wars last year. The ROI on those went from "great" to "very modest" overnight. I know there is an RI Marketplace where I could try to sell them, but as the on-demand prices went down so far, I would not be likely to get a decent deal. It felt like the best customers, those who have committed for multiple years, were being left out in the cold. I will not be doing any long-term (over 1 year) RI purchases again unless they make it possible to participate in price drops.
