Overview
The order rule action UseProductCostInPlaceOfPricing will allow you to use the CostPrice field instead of the Price field, this Order rule action will apply to all products on the order. This can also be useful if you are importing orders from a custom Mintsoft API, you can use this order rule action to use the cost price for products (By default it won't pull the sale price if no price provided in the request).
For Example
Product: Bottle of Water.
CostPrice: 1.
Price: 2.
If the Order Rule were run, it would display the CostPrice of 1 on the order instead of the Price 2
