This case study analyzes strategies for a sales promotion of hair care products by Boots stores in the UK. It considers the hair care products market, competitors, and three potential strategies: a "3 for 2" deal, a gift with purchase (GWP) promotion, or on-pack coupons. Market research estimated that the "3 for 2" strategy could increase sales by 300% while the GWP could increase sales by 170%. While the GWP may be commonly used, the "3 for 2" promotion would boost sales volumes more and increase brand consumption without being easily imitated by competitors. Therefore, the "3 for 2" strategy is concluded to be the most profitable option for Boots.
