(15996180) Coupons that have a Coupon Usage Limit = 1 value, are not limited to single use.
When you add a coupon that has the Coupon Usage Limit set to1, it is applied to the order. However, once the order is submitted, the coupon can be re applied to another order. This is because the coupon adds its promotion to the user’s activePromotions, however the promotion is not deleted once the coupon has been used because coupon usage is not verified in the PromotionsTool.
