How do I create a coupon for a special occasion?

If you want to put out a coupon that can only be redeemed on a particular day, such as a holiday, you need to set the redeem-by date of the coupon to that particular date (such as February 14th for a Valentine’s Day special). Please note that this limits the time a customer can redeem a coupon, but the coupon will still be applied to the next invoice generated after redemption, whether or not it occurs on that day.
