The 4th step when setting up your AppScenic Account is to configure the Default Price Formula for all the products in your store. 

To do that click on Default Price Formula on the Quick Start section of your AppScenic Account or go to My Products, then Price Formulas.

AppScenic Formulas help you set certain specific rules for the prices of one or more products. With Price Formulas, you can either choose to make a profit and increase the price for a range of products or offer a discount and decrease your price for some products.
