Free order would be something didn't go right and to make the customer happy they just gave it to them. Perhaps there was a donation.

I called for specifics on quantity discount. He wanted to remove the quantity discount on a large order he sold at a special price. For example a pizza normally cost $10. A school called and wanted 10 and he sold them for $6.00 each. So he edits the order and makes each pizza $6.00 each. But because he has 10 pizzas he cannot get rid of the quantity discount. He has to figure out how much each pizza should cost before the quantity discount. I guess we just have to work around this now that we know what to expect.
