You always earn 10 points for every dollar you spend on eligible menu items, regardless of whether you order a combo or not.
If you’re eligible to get a reward, and this reward item is part of a combo or other menu discounts, your points will be applied in the manner that results in the highest discount.
The highest discount is always given, whether it is the combo discount or the redemption of the Reward. If the combo discount is greater than the discount from getting the Reward, the combo discount will be applied, and the points will be saved for the next eligible purchase.
