Promotion on conditional quantity of products in basket

Addon to CS-Cart and Multi-Vendor allow to set up promotion for some products, depending on other product. For example, a base product is a software license, and bonus is possibility to choose some add-ons to chosen product, with a discount.

We start from installing an extension:

Next we configure extension. Amount of products defines the maximum possible amount of discounted products. Page ID allows to redirect customer to special page where promotion conditions are explained:

Then we configure promotion. In conditions we choose the base product and additional condition:

In bonuses section we set how many products can be discounted and which product are part of promotion, and how high is discount value (in our example additional products are for free - 100% discount):

Customer after adding base product to cart will get a notification, that he can take part in promotion, and link to promotion conditions will be displayed:

After adding to cart products, that are in promotion they are properly discounted, as seen in cart (in our case discounted products are for free)

If there will be no page ID defined in add-on configuration, link will redirect customer to list of promotions.

Enjoy !
