Coupons play an important role in the sales strategies of many different businesses. Often, businesses will run promotional campaigns that reward customers with coupons, vouchers, or codes. Customers can then use them when they shop.

Typically these coupons and vouchers offer customers a percentage discount on a product, or their entire purchase. Sometimes they have a monetary value instead, or they can be exchanged directly for products. These are all examples of redemption.

Many promotions come with lengthy lists of redemption terms that restrict the circumstances under which promotions can be redeemed. Common redemption terms include:

• Promotion only valid within a certain date range
• One redemption per household
• Promotion only valid for residents of a certain country
• Customer must provide valid email address
• Promotion cannot be redeemed in conjunction with another promotions
  

Redemption terms serve an important purpose for businesses running promotions. They help maximize the value of promotional campaigns by protecting against overuse. They do this by giving businesses better control over when and where promotions can be used.

While most of these restrictions are built into the backend of promotional campaigns, it’s important to make sure customers are aware of restrictions before they try to redeem their coupons. An unexplained coupon rejection could damage the relationship between you and your customer. To avoid this, it's important to make sure terms are properly communicated beforehand.
