Points do expire on a rolling one-year basis, but Rewards do not expire.
You will receive an email when you earn enough points for a Reward. Once you earn a Reward, you must access your account on our Site, and claim the Reward. You will immediately receive a promotional code that you can use on any future purchases.
Your Points will expire on a rolling one-year basis. For example, if you earn Points on October 1, 2015, those points will expire on October 1, 2016 (the "Earning Period") if they have not been used towards a Reward (i.e. you did not earn enough points during the one-year period).
Once your Points have been converted to Rewards, they will never expire and may be used toward future purchases as specified in these Terms.
