Similar to how normal quantity pricing works, this addon can apply a single "plan" to multiple products.  Additionally, a "plan" can be assigned to a category and all products within that category can be assigned to that plan.

Main features:

• Discount Plans are managed by name and assigned to products
• All products within a cart that belong to the same Discount Plan will have the total quantity of those products used to determeine the discount for each product.
• Plans can be adjusted independent of products so a plan can be change and affect all products that are assigned to that plan without having to edit the products individually. Discount Plans will replace the standard Quantity Pricing.
