Merchandising tactics, which address the effective packaging and positioning of goods, have long been deployed within retailing to stimulate customer demand.

The principal penalty incurred by past caution is that decision making is now hampered by the scarcity of good quality merchandising research. Nevertheless some retailers have decided to move to glass-fronted chilled cabinets to display their beverages. Alternatively, such products are placed on shelves at eye level or, potentially more tempting still, near checkouts.
