You may include up to 50,000 coupon instances in one single-use coupon series.
You do not need to create all coupon instances for a single-use coupon series at the same time. Additional coupon instances may be added to a series after the series is created.
After adding the additional coupon instances, you may download an updated list of coupon codes for the single-use coupon series, or choose to return to Coupon Manager.
In order to create a single-use coupon series, you must begin the series by creating at least two coupon instances. If a coupon series is created with only one instance, it will not be recognized as a coupon series, and you will not be able to add additional instances.
When only one single-use coupon instance is created for a coupon prefix, the coupon code will contain the prefix only, since additional coupon instances cannot be added at a later time. For example, if you enter a coupon prefix code of myoffer and create one coupon instance only, the coupon code will be myoffer.
