Currently, customers are responsible for paying the shipping costs. The sales team suggests that customers really dislike paying shipping costs, and that offering "free shipping" instead of the 1% discount would likely increase sales. Create a formula for the "Sales with Free Shipping" column that subtracts the "Shipping Cost" from the "Sales" only if the "Expanded Order Type" is Extra Large, XX Large, or XXX Large. Copy the formula down to all the rows. What would total 2012 sales have been if the company had offered free shipping instead of the 1% discount (rounded to 2 decimal places)?
