Directive (EU) 2019/2161 of the European Parliament, also knows as the EU Omnibus Directive, introduced among other things the requirement to display the lowest price of a product in the last 30 days, including any discounts or promotions. This information must be clearly visible and easily accessible to consumers before they make a purchase. This plugin does exactly that.
