A coupon pool lets you distribute pre-registered coupon codes to visitors one at a time. Once a code has been distributed, it is marked as "used" and will not be reused.
Steps
Click "Coupon," then click "Create New Coupon Pool."
Enter a name for the coupon pool and click "Create."
Click "Edit" on the coupon pool.
Click "Add Coupon Codes."
Paste one coupon code per line, then click "Save."
This completes the coupon pool registration. Once a coupon is shown to a customer, its status will change from "Unused" to "Used." You can also delete coupons from this screen. Next, set up the coupon pool on the display.
In the display's coupon content, select the coupon pool you want to use and click "Set."
Save the display settings.
