Thanks for your prompt response, here is the link of beta page I'm working with (private area). Please don't go through checkout process i just have the add to card and update functions working.
You will notice when you add the product to cart it will bring up some add-on options.
Now if i add an item that is not an add-on option I would like the discount to show only on products not add-on items.
The discounts will be given on qty 25, 50,75, 100 so if the client adds or updates a qty of a specific product if they reach the qty stated a discount will be applied.
