If you have set up a multiple coupon code promotion and want to allow customers to make more than one booking with the same coupon number:
1. Go to Marketing>Promotions, and click on the promotion
2. In the Coupon codes section, tick the Allow duplicates checkbox. You’ll need to upload the same coupon for each booking allowed with that coupon. For example, if a coupon allows 3 bookings, upload the same coupon 3 times.
