I heard an interesting story on NPR the other day on how Amazon is using a dynamic pricing algorithm that can radically change the price of an item over time.
Now, in my own experiments and from what I’ve been told from IT people who actually work at Amazon, they do not do targeted pricing for individual users. For example, I was looking a purchasing a particular television and I asked on Google+ for people to check the price from their point of view, and they all came back with the same number.
But I thought this would be a simple job for OpenNMS to track a price, and it was. I wrote up the details on the wiki if you want to check it out.
