I need to create a cart price rule which will be applied only if:
- Subtotal is greater than 2000.
- The products forming the subtotal must be non-discounted.
- The products forming the subtotal must belong only to certain categories.
All 3 conditions are necessary. For example, if subtotal is greater than 2000 and includes 2 products, one discounted and other non-discounted, than the discount should not be applied. Also the discount must be applied only to products satisfying the above 3 categories.
