Manufacturer Coupons adds support for assigning coupons not only to products and categories, but also to manufacturers, including strict manufacturer-based category filtering. This allows store owners to create targeted promotions for products from specific manufacturers, enhancing marketing strategies and boosting sales.

Compatible with OpenCart 2.3.x (PHP 5.6) and 3.x (PHP ≥ 7.x).

Features
* Assign coupons to specific manufacturers, including strict manufacturer-based category filtering.
* Single manufacturer mode — coupons are applied only when cart products belong to categories of the selected manufacturer.
* Fully integrated with default OpenCart coupon logic.
* No core modifications required.
* Seamless compatibility with the **Journal** theme.

Disclaimer
The extension has been tested with the default OpenCart structure and theme. However, third-party themes or extensions may cause incompatibilities and may require additional tweaking to fix. The developer is not responsible for such issues and is not obliged to fix them, but can do so for an additional fee, to be discussed separately.

Restrictions
This module does not work and is not supported for stores using the following domain extensions: .ru, .рф, .рус, .by, .бел, .su.

Live demo
