I know this is not as good as the Morrisons Ariel 18p deal but thought i'd mention it anyway for those of you that missed out - Just been to my local Tesco Express ( Stenson Road ) in Derby, they had their Fairy non bio 20 wash tablets reduced from £6.00 to £3.something and now to £1.89. They had about 5 boxes on the shelf.
I have no idea if this is nationwide at the Tesco Express stores. I'm sorry i don't have a receipt or picture as proof for you non believers. The price on line is £6.00.
