During redemption of points from Tiered loyalty program, you must be aware of the following:
You can choose the tier from the Loyalty Program field (if the guest has points accumulated from more than one tier) from which the points must be redeemed from.
The points of the selected tier which are set to expire first are redeemed first (this is by design).
The guest cannot use points to pay tips, memberships, and pre-paid cards.
Points redeemed from Tiered loyalty program are always redeemed on the post-tax amount (unless configured for closed invoices. For more information, see the Closed Invoices in a Tiered Loyalty Program article).
