Apologies if this is a repost - I searched and nothing came up.
Just nipped to Morrisons and noticed they are selling a variety of the 750ml Copella juices for 50p. Down from £1.79 I think the label said.
Flavours that I know are included:
Smooth orange (no bits)
Pink Apple lemonade
There may well be more, but the above are the ones I picked up.
Worth a try at this price :)
