Starbucks announced 11% year-on-year growth in sales for April, the sixth consecutive month of gains of 10% or more. The company attributed the growth to a combination of new drinks, shorter waiting times for customers and strong performances from its drive-through cafes. The company reported net revenues of $395m (£222m) for the four weeks to 25 April, up 29% from the same period a year earlier, and said its worldwide cafe chain grew to 7,912 units in April, a net increase of 78. Although Starbucks said last week that operating costs were rising, in particular that of milk, no price rises are planned.
