title: Amazon API submitting requests too quickly
body: <p>I am creating a games comparison website and would like to get Amazon prices included within it. The problem I am facing is using their API to get the prices for the 25,000 products I already have.</p>
  
  <p>I am currently using the ItemLookup from Amazons API and have it working to retrieve the price, however after about 10 results I get an error saying 'You are submitting requests too quickly. Please retry your requests at a slower rate'.</p>
  
  <p>What is the best way to slow down the request rate? </p>
  
  <p>Thanks,</p>
