Mobile Coupons are included with any mobile website if wanted. The coupons are redeemed by the user showing the coupon on their mobile phone screen when ordering, paying or when receiving a delivery order such as a food delivery. This encourages the user to view your mobile site and become familiar with it which has a powerful marketing impact.
