bulk download of amazon product prices

Description I need a scalable solution that will enable me to retrieve large quantities of amazon product prices for my soon-to-be comparison site. For my csv file of 100,000 products, I will need this program to use an amazon api to retrieve product information on a product's price, and possibly a few other key items. Requirements: +Use of an amazon api and not simply webscraping +Done efficiently and scaleably, so the 100k items can be updated in as little time as possible +Python coding strongly prefered +If there are Amazon-set throttle limits, these need to be clearly stated.
