Final answer:
An action in a loyalty campaign might include punch cards for repeat purchases or free gifts with a number of purchases, both designed to retain customers and encourage loyalty.
Step-by-step explanation:
An example of an action taken in a loyalty campaign could be when a retailer offers customers a punch card, where a purchase gets a punch and after a certain number of punches, the customer earns a free item or a discount on their next purchase. This incentivizes repeated purchases from the company and encourages customer retention. Another example might involve a coffee shop giving away a free coffee mug after a customer purchases a set number of coffee drinks, thereby promoting brand loyalty and encouraging future sales.
