To stay compliant with Amazon, you have to use their Product Advertising API to display prices and product info. Most people use plugins like AAWP or AmaLinksPro to pull in that data.
However, even though these plugins use shortcodes to speed things up, you still have to manually enter in the ASIN each time you build a new box, list, grid or table.
Amz Table Assistant saves you time and guarentees consistency. No more switching tabs, no more manually formatting shortcode, & no more trying to remember the correct syntax.
