Convenience retailers are missing out on thousands of sales a week because shoppers leave stores without finding what they want. This was one of the findings of the latest CTP research carried out by Harris International Marketing. Interviews with more than 1,000 shoppers outside c-stores discovered 17% went in intending to buy milk but only 14% actually bought it. Similar findings were reported for cigarettes. HIM estimated the cost of lost milk sales alone to the c-store sector was about £20,000 a month. Tom Fender, general manager of HIM, warned: "It is evident that customers want the convenience of shopping locally but they could be driven away if the problem of non availability continues to exist." {{NEWS }}
