Final answer:
The BEST way to inform customers about a frequent shopper program is through direct, informative communication by sales associates, supplemented with in-store marketing materials like signage, flyers, and prompts at checkout.
Step-by-step explanation:
The BEST way for a sales associate to inform customers of the store's frequent shopper program is through direct communication, either at the point of sale or during interactions on the sales floor. For instance, after helping a customer find a product, the associate can mention the benefits of the program, such as discounts, exclusive offers, or reward points. Another effective method is including information about the program in the store's marketing materials, such as shopping bags, receipts, and flyers, as well as through an email newsletter for subscribed customers. Additionally, in-store signage and prompts at the checkout counter can serve as visual cues to initiate the conversation. Training staff to understand the program thoroughly ensures they can answer any questions and help customers see the value in joining.
