Walmart has teamed up with Procter & Gamble in a month-long promotion of online and mobile shopping in New York City.

A lorry covered with QR codes for several P&G products, including Bounty paper towel, Head & Shoulders shampoo and Lams dog food, will tour the city. New Yorkers can use their phones to scan the products, which are instantly added to their basket.

The truck will visit a dozen locations throughout June. Consumers can request through Twitter that the truck visit their neighbourhood.
