Instructions:Saw this voucher on one of the pop-out cardboard displays which advertise the Weetabix products as well as the new Toy Story 3 movie.
The vouchers are stuck to the top of the display. Just grab one, and get 35p off of Weetabix, Weeto's, Oatybix and Mini Weetabix.
No end date as known. Just as long as the vouchers last.
