1. PriceZombie was not built on top of Amazon. PriceZombie indexes products and prices in over 100 online retailers. The developers always had the option of using the PZ website as a front end to gather personal shopping habits and other data that is valuable to advertising and marketing companies - which is what many (most?) price trackers do as their primary source of revenue. PZ opted to get their funding from retailers instead. People purchased mostly from Amazon, therefor when Amazon pulled their affiliate program funding dried up and PZ had a choice - go to the dark side, close up, or sell. 2. They had many contacts, some of them quite high. PZ is a very ethical and methodical company. They dotted their i's and crossed their t's. They had an open dialog with Amazon where they were repeatedly told, in writing and on the phone, that they were in full compliance and there was no problem. The problem with Amazon is inconsistent and arbitrary enforcement of their own rules. The developers are in discussions now with companies that want to purchase the technology - including my own, though I don't think we can afford them. This is no garage set up by comp sci students. The developers have impressive credentials and they have created a very impressive system that has wide application to other uses.
