Superdrug have their own brand of nappes (Snugglers) on offer at only £2.86. I got the Junior Size 5, which contained 27 nappies, but they had all sizes available (newborn, mini, midi, maxi, maxi +). Less than half the price of Pampers and with more nappies! Don't know if this is nationwide, I spotted this fab deal in Wimborne, Dorset.
Snug fit waistband - Stretchy resealable tapes - Soft breathable cover
Shaped Ultra Absorbent Core - Anti Leak Leg cuffs - Got to be worth a try at this price!
