Volume Discounts Online Store Promotions Bulk Pricing
How can I give bulk pricing discount on 2 items within a category that is grouped with other items that do not have bulk pricing?
You are able to add those two items to an entirely new category and suppress the visibility of that category to Internal, so it won't appear in the store. Then you can build in a volume based discount for that new category. When a customer goes to the original category and adds each item to the cart, the discount will take affect because of what was arranged in the 'hidden' category.
