Effect of discount sequence on discount eligibility

If two check-level discounts are on a check, one of those discounts must be a nonexclusive discount. Whether the discounts can be combined depends on which discount is applied first.

If the first check-level discount is nonexclusive, then none of the items are marked as used up. The second, exclusive check-level discount can then use those items and mark them as used up.

If the first check-level discount is exclusive, then all of the items in the check are marked as used up. When you apply the second, nonexclusive check-level discount to the check, the effect is as follows:

  • If the second, nonexclusive check-level discount does not have a required item, the discount applies, because it can be combined with other discounts and does not need an item in order to be applied. In this case, the order in which you apply the discounts does not matter.

  • If the second, nonexclusive check-level discount does have a required item, the discount does not apply. The first, exclusive discount item marked every item as used up, and did not leave any items for the second discount.

    In other words, although a nonexclusive discount can normally be combined with an exclusive discount, in this case it cannot because of the requirement for an item that is not used up. In this case, the order in which you apply the discounts does matter.
