[Plugin: Advanced Custom Fields] How can I add shopping cart or other values to Custom Field

Hi, I would like to use this plugin but first I would like to know how I can add eshop Product’s Description, Price, SKU, Stock Available and options or other values to the Custom Fields? I am using a front-end editor and would like to have this added to Custom Field.
