No. For as long as you are a member of your program, you can use your points balance whenever you wish. Our Rewards Catalog offers many different rewards, so you can save up points for larger rewards or opt for smaller rewards whenever you like. The choice is yours.
Note: In the event that you become ineligible to be a member of your program, you may be given a grace period to use your points before your account is disabled. This would be the one case where you may want to spend your entire points balance at once. You can get more information in the program-specific FAQs or by contacting your program administrator.
