This module has been specifically designed to help you assign carriers to products in bulk. And it’s completely FREE!
Assigning specific carriers to products is a long and cumbersome process, but this Free PrestaShop module lets you do it in a single click for whole categories or chosen product lists.
You can select two different input modes (by category or direct input of a comma-separated list of IDs), the carrier, hit assign, and you are done! Take the work of hours down to a couple of minutes!
