Every coupon has an expiry date which is mentioned in the "Fine Print" when purchasing a deal. It is your responsibility to read the "Frine Print" and you are agreeing to the deal's terms and conditions when purchasing your coupon. We cannot offer refunds for expired coupons.
Although the merchant is not required to honour expired coupons, you can try your luck and give them a call to see if they will accommodate you.
If you know that you won't be able to use your coupon before its expiry date, you can gift it for someone else to use. Coupons can be redeemed by any person holding a valid coupon, regardless of the name printed on it.
