Found this on offer in store and is also mentioned on the B&M website.
22 wash box of Ariel Powder for £1.99 (works out about 9p per wash)
"Ariel with a Touch of Febreze.
Cleans, lifts stains & brightens.
Outstanding stain removal in the 1st wash."
My store had this plus the Ariel Actilift (with a touch of Febreze) at the same price of £1.99 (from £3.99)
Currently £4 in Tesco and £6 in Asda.
My purchase was in a Belfast store but as its on their website this should be national if your store has stock.
