Cross-merchandising your products is a great way to increase sales and customer satisfaction. You can group products by category, theme, or occasion, and use signage, banners, or labels to draw attention to the complementary products. Additionally, you can place cross-merchandised products near the checkout, in the aisles, or on end-caps. To maximize the effectiveness of cross-merchandising, train your staff to cross-sell and suggest add-ons. They should ask open-ended questions, listen to the customer's needs, and recommend products that match their preferences and budget.
