The discount will be applied amongst all items within that Promotion and distributed to each item based on their original sell price minus item discounts, subtotal discounts and surcharges.
The following formula applies to all Promotion Discounts.
Using this formula, we can apply that to any item included in the sale affected by the promotion.
For example, if we sold Becks for $6 and Corona for $4 for a total of $10.00 with a 40% discount, the formula would apply to each item as follows.
Becks
Corona
The Discount Amount is $4.32 and will be divided equally between all items within the sale relating to the promotion.
Any other items will not be affected.
