Schweppes lemonade is running a promotion based around its sponsorship of the McLaren Formula One team. The promotion ­ featuring on limited edition silver two litre bottles (regular and diet) ­ gives consumers the chance to instantly win a Mercedes A Class car, one of 25 Tag Heuer watches or one of 3500 replica sports bottles (as used by Mika Hakkinen). It starts on March 27 and runs for eight weeks. Patricia Macnamara, channel marketing manager, grocery, Coca-Cola Great Britain, said the promotion would drive trial of Schweppes and generate interest in lemonade and in turn drive sales. {{P&P }}
