Can Loyalty Points or Tiers Expire?
Your points will expire after six months of inactivity. So as long as you make another purchase (even if you don't use your points), you'll retain your points for 6 more months.
Loyalty Tiers will expire after 12 months of inactivity. To maintain your status, you must make another purchase within that time frame. Once a purchase is made, you'll retain your status for another 12 months.
