WordPress Automatic Plugin has the option to grab Amazon products to WordPress and optionally post it as Woo-Commerce products.

Unfortunately, Amazon limits the number  of returned products for a specific API query and although the plugin scrapes Amazon for more after all API results were posted, Amazon also limits the number of items for regular visitor as well

one good way to post more is to collect ASINs for Amazon items and tell the plugin to post from.

To get ASINs for items displayed at any Amazon page, Use this awesome chrome extension named “Asin Grabber Light”

once installed, visit any Amazon page that contains products and click the extension button

Now simply copy and paste these ASINs to the plugin keywords option
