OpenCart - how to make a group of users who can buy goods from a specific category with a fixed discount?

Question

CMS

CMS - opencart. You need the ability to add users registered in the online store to a specific group (for example, VIP). Those users who are added to this group always buy goods from CERTAIN categories with a fixed 20% discount.

How can this be implemented?
Is there such a solution in the form of a plugin or something else? Thanks in advance

Answer 1

goods from CERTAIN categories with a fixed 20% discount.

This cannot be done using standard OpenCart tools.
You can only create a promotion in the product card for a specific group of customers with the required discount. But this must be done for each specific product, not for the category.
Another option is to install the Bulk Price Management module
