Issue
It is impossible to apply a cart price rule based on Subtotal (Incl. Tax) number.
Step to reproduce:
- Configure product price to include tax.
- Create a tax rule and tax rate for 20%.
- Create a product with Price = 100 (this price includes tax).
- Create a new cart price rule with a coupon "10off" to apply $10 fixed discount if subtotal matches these conditions: Conditions : If ALL of these conditions are TRUE : * Subtotal equals or greater than 100.*
Expected result:
There is ability to create a subtotal cart price rule with coupon to apply discount to subtotal including tax.
Actual result:
There are two options in cart rule conditions: Subtotal and Subtotal (Excl. Tax), and whatever one is selected, the rule is applied only to subtotal excluding tax.
