Do redeemed coins expire when converted to a coupon?

Yes. When you convert coins into a coupon, that coupon comes with an expiration date, so it is worth checking the terms before you redeem.

• Coupons expire: every coupon redeemed from coins has an expiration date.
• Check before redeeming: note the expiry so you can plan to use it in time.
• Fixed once issued: after a coupon is created with an expiration date, that date cannot be extended or removed.
