 * Hi,
    after Amazon updated the Efficiency Guidelines (see [https://docs.aws.amazon.com/AWSECommerceService/latest/DG/TroubleshootingApplications.html#EfficiencyGuidelines](https://docs.aws.amazon.com/AWSECommerceService/latest/DG/TroubleshootingApplications.html#EfficiencyGuidelines))
   the plugin started giving lot of the following errors in php-errors.log
 * (Translated by Google translator from Italian language, maybe the english error
   is a bit different)
    `<h4> You are sending requests too quickly. Try sending 
   requests less frequently. For more information, see the <a href=http://docs.aws.
   amazon.com/AWSECommerceService/latest/DG/TroubleshootingApplications.html#efficiency-
   guidelines target=_blank> Efficiency Guidelines </a>`
 * I think you should add some kind of caching to the plugin, because it sends too
   many requests to the AWS E-Commerce Service.
 * Best,
 * Nicola

 * Dear [@nicolaottomano](https://wordpress.org/support/users/nicolaottomano/),
 * The error: “You are submitting requests too quickly” is due to throttling. This
   has to do nothing with this plugin update. Please check if you allowed request
   count has reduced for any reason. You can write to Product Advertising API by
   filling form at [https://affiliate-program.amazon.com/home/contact/](https://affiliate-program.amazon.com/home/contact/)
   and select Product Advertising API from the subject.
 * We are already using caching that caches an Ad generated from shortcode with 
   maximum TimeToLive(TTL) of 30 minutes as per Product Advertising API Operating
   Agreement.
