Points are valid for 36 months from when they are earned. After that, they automatically expire and will no longer appear in your points balance. You also won’t earn (or may lose) points if a purchase is returned, cancelled, or unpaid, or in cases of misuse. Certain purchases like shipping costs and gift cards are excluded from earning points. If your membership is deactivated or terminated, any remaining points will expire. Points that you’ve already converted into vouchers are not affected.
