Cross-merchandising can increase basket sizes and average order values. The practice encourages product discovery and encourages shoppers to consider items that match their existing purchases.
One way is to sell items that are compatible. For example, you could create a display that includes a blouse, jacket and matching purse.
Promote slow-moving products. Do some research into what products are selling slowly and then take the time to pair them with complementary faster-selling products. For example, if a certain gardening shovel is barely selling, display it next to a popular plant.
