Dave Robinson is evaluating promotional strategies for Boots' line of professional haircare products. The options are a "3 for 2" deal where customers get 3 products for the price of 2, a buy-one-get-one-free deal, or a 50p on-pack coupon. While the "3 for 2" strategy has the lowest estimated profit increase, it has the benefit of being unique to Boots and harder for competitors to copy. Considering Boots' relationships with celebrity hairdressers and the importance of protecting its leadership in the haircare segment, Dave decides that a "3 for 2" promotion is the best choice.
