Auto-Updating Amazon Affiliate Links

I need Amazon Affiliates integration added to each product page so that the price, availability, and buy button all update automatically whenever Amazon changes them. The goal is to stay compliant with Amazon Associates while keeping my catalogue accurate without manual edits...
