Do reward points expire?

Yes, reward points expire 1 year after they are earned.

Every account holder has the option to enroll in a points expiring notification that will email you 7 days before points in your account are set to expire. You can opt-in to these optional email notifications by logging into your customer account, selecting My Reward Points from the account navigation menu, checking the box under Notification options for the Receive emails when reward points are about to expire option, then selecting the Save Notification Options button.

You can also see the time remaining to use earned reward points in your account under My Reward Points.
