The commerce price table module is meant for calculating the sales price on commerce products based on order quantities. But out of the box the contrib module commerce_price_table prices do not get calculated to sales prices. In my case I have a tax rate per product that is nicely applied to the standard commerce product price but not to the commerce_price_table prices.
Is there another way to calculate the product sales price based on order quantity? Might this be fully configurable with Rules?
