When editing a combo a few of the steps differ from other menu item types. A user may edit the following:
Name - Enter a name for the menu item.
...
Apply Discount After Taxes - Check to apply a discount/prevailing price to this menu item after taxes are applied. (This check is going to be removed in the future. Combo Discounts are always applied before taxes)
Taxed For Takeout - Check to have this item taxed when ordered for take away.
