Women shoppers are more profitable for c-stores than men but expect higher standards and lower prices according to a new report. Harris International Marketing's latest shopper survey ­ Sex in c-stores ­ suggests women spend more than men and visit their local c-store 16% more often. The report found that women take responsibility for general household shopping, with a third saying they bought from c-stores because they had "run-out". Fresh products such as bread and milk were top category purchases. Men were more likely to shop at c-stores because they felt "hungry or thirsty right now". Over one in four men surveyed bought snacking and impulse products like chocolate bars, crisps, snacks and newspapers on impulse. Neither sex has much idea of the actual costs of products in c-stores and both appear willing to pay a 14% premium for convenience, said the report. {{NEWS }}
