Hello,
Prices per product are given on my product page. It is located at the top. As in photo number 2. However, I want to write the total number of selected pieces together with their discounted price in the lower section, as in photo number 3.
I kindly recommend you to build Custom Single Product layout, which is built with WoodMart WooCommerce builder, then you can re-order product content positions without using Custom PHP code.
