Spotted in store in Bradford . Possibly nationwide.
Works out cheaper than Morrison's £9 Jumbo packs.
Example: Morrison's Jumbo Size 4 has 86 Nappies that's 900/86=10.47p per nappies.
Asda Giga Packs size 4 has 120 Nappies that's 1000/120=8.33p per nappies.
Or you could say with the giga pack you get 34 nappies more for £1.
