UK chocolate maker and distributor Thorntons has reported sales up 3.7% from £159.9m to £163.8m (US$258.6m) in the year to June. Cooler than usual weather gave sales a boost, while a new 'present for the teacher' promotion also gave sales a shot in the arm. Like for like sales improved 3.6% in the group's own stores, while sales through franchises and the group's website improved at an even higher rate.
