Now each deal you offer can have multiple different coupon types which is perfect for letting your businesses offer a variety of deals to entice all market segments. For example if a restaurant is offering a deal then the business owner can offer a coupon for couples, a coupon for families and a coupon to get businesses to take lunch in their establishment.
Another way you can use sub deals is to offer the same coupon but for different prices. For example a business could offer 5 coupons with a 50% discount, 10 coupons with a 25% discount and so on. This creates scarcity of the offer and encourages people to buy the deal immediately rather than waiting to see how many other people are going to buy it.
