I am looking for a script that can query amazon at a preset interval (every 4 hours, every day etc thru a cron job) and save prices in a database. I should be able to specify categories that I want, and # of top-selling products in that category should also be configurable. For example, I should be able to config the program to log the top 1000 selling ASINs in electronics and top 500 selling ASINs in software daily. I would like to log the entire price history for the past 3 months (assuming I run it daily). If that's too much at least I want to log max price, min price, average price and current price; as well as date of max price and min price. Perl/Mysql solution is preferred but PHP/Mysql is fine too.
