Promotional codes are a string of numbers and letters that shoppers can use to enjoy certain benefits, such as discounts on their purchases, free shipping, or gifts. Depending on the purpose of the promo code, access can range from publicly available to restricted to a specific customer.

Promotional codes are alphanumeric strings that online stores offer to encourage purchases on their website and are typically associated with an overarching promotional marketing strategy. The discount associated with a promo code can apply to individual products or an entire order.
