Oh, man! We hate hearing that! You will receive a points expiry notice 30 days before the final chance, then 3 days before the expiration.
The good news is, keeping your points balance from expiring is SUPER easy! Points are set to expire after 180 days of no points activity - that's about 6 months! In order to keep your points balance going, all you need to do is earn or spend points at least twice a year :)
Once you have activity on your points balance, the entire balance's expiration will be extended. There are some great ways to earn points - for more information, check out our article: Getting More Points
