printed order reciepts need to show the calculations, not just line totals. for example:
widget $10 qty 2 total $20
instead of the current:
widget qty 2 total $20
even though it’s quite easy to do the math on a simple price like $10, customers often ask how much they are paying per item. imagine if the customer in this example had a 33% discount, each item became $6.67 and the total was calculated accordingly.
