Does anyone know how to get Amazon price history data like on this page?
I am looking to do something similar, but have no idea where they’re getting the data from. Thanks.
I know I’ve seen/heard of sites that simply crawl shopping stores like Amazon constantly and maintain their own database of information. If you Google for Amazon Price History tools I’m sure you’d find a few services that offer it, although they might not explain their process to the competition 
I also know there is an Amazon Product Advertising API that might provide useful data - but I know nothing about it. I have no idea if there are other methods of doing it.
I don’t know much about crawling–I have working knowledge of php. Is it legal to simply download the page daily as a string and then search the string for the process?
