Much of the Don Simon fresh juice (not concentrate) range in Asda is on offer at 2 * 1 litre cartons for £1.50 at the moment. Examples include:
Orange (smooth or bits)
Just had 2 cartons of smooth orange juice delivered today and it tastes pretty good (different to concentrated juice if you're used to that) - 75p for a litre of fresh orange juice seems very cheap to me. I'm assuming this offer is in the Asda offline stores too.
