The module does the job perfectly.

It allows you to implement both wholesale trade on the site and create a normal loyalty program for regular customers. It is strange that there is no such solution in the opencart out of the box, but the price of this module is low, the installation is simple, the setup is primitive and understandable.

The only drawback is that at first the module did not work and pulled failures on the site, I must admit I was tense and upset. But the developer quickly responded and provided the necessary file suitable for my version of php 7.2 and this completely solved the problem.

As a result, the module is fire, the developer adequately and quickly resolved the issue. So I absolutely recommend it.

P.S. Given the cost of the module, the very first wholesale order pays for it, a little more than completely.
