Been munchin on these for the last week or so now - available in store or online at Tesco are Fox's "Rocky" bars (like Penguins or Clubs). You can get a 10 pack of them for just 49p which is half price. Three varieties - Chocolate, Caramel or Chocolate Orange. At just 5p a bar its great value and very very yummy. Snag em while u can!
Penguins are also half price - down to 59p a pack of 9!
