Popped into Asda there and noticed they had a pallet of twinpack tuna for £1. Absolute bargain. Usually their offer would be something like £2.79 for 4 so now you can get 4 for £2. Its likely to be Nationwide. I got them in Asda Cookstown Northern Ireland.
The picture is of a 3pk, I cant find a picture of a twinpack.
Its the Tuna chunks in brine 2pk
