In this chapter, we have learned how to define and activate coupon codes. We created coupons with fixed amounts or percentages. We could limit the usage of coupons with numbers or according to the total amount of customer shopping cart. It is also possible to offer a coupon with free shipping.

We have seen that it is also possible to create discounts on selected products for a time period. OpenCart system also allowed us to define discounts for different customer groups, such as wholesale, VIP.

In the next chapter, we will learn how to handle orders, change order statuses, and inform customers about the order statuses.
