Hi people! This addon I have done allows you to link a product with another product. Hence when you click on the buy button on product A product B will be added to the cart.
1. When you click on delete for product A or B it will work out the total you have left for prdocut B if its zero it deletes that product from the cart.
2. When more Quantity to Product A product B will be added too however product B will not acceft product A Quantity.
3. You can have alot of product link with product B.
3. When deleting either Product A it works quantity value of B by product B minus product A and deletes product A.
Basically what it does is allows merchant to sell a product which force the customer to buy the other product.
