Finish all in 1 Powerball Dishwasher Tablets (Lemon) 26pack with 100% Extra Free for £4.00 in Tescos. Online too but not the extra 100% packs. 52 Tabs worksout nearly 8p each. (Image is 30+30 as couldn't find 26+26).
Standard 52 packs are £6.25 so keep an eye out for the promo packs saying 100% Extra free..
Found these in Tesco Kingston (MK)....
Better than the Lidl / Asda deal published few weeks back.
