Pepsico has introduced pre-merchandised clipstrips for its four best-selling variants of Walkers crisps: salt & vinegar; cheese & onion; ready salted; and prawn cocktail. The strips are available in boxes of three with eight packs on each strip. It is hoped the initiative will drive additional sales of up to 30%. A marketing campaign which includes sampling, TV and social media activity will run in September. tel: 0118 930 6666
