Admittedly not the cheapest brand of rice out there - but I find Tilda a lot nicer than other brand names/supermarket owns.
It's normally £4+ for the 1kg bag, down at £2 until 1st August in Morrisons.
Nationwide offer I believe.
Plenty of stock in my local (Fishponds, Bristol).
Seems to be £3 in tesco at the moment for the same bag - still a good deal if no morrisons nearby.
Been REDUCED AGAIN DOWN TO £1.88 now.
