It is possible to define for each collection which product of the site's products should be given as a gift.For example, we have categories of laptops, mobile phones, bags, etc. on the site. Now we want to give people who buy laptops a bag that we choose from among the bags on the site along with each laptop.Note: The gift is among the products of the site, and it is possible to define a separate gift for each category, and the gift can be displayed in the products and also displayed in the shopping cart with zero price.
In my opinion, such a plugin is much needed in J2 CommerceBecause most of the store builders have the ability to gift along with the product.

Thank you very much for the development of j2CommerceThe price of the product that is added as a gift to the main product should be zero, but if the gift is purchased separately, he must pay an amount according to its price.
