Double discount on a few varieties of pampers at boots.
By my maths this works out at 14p per nappy including free delivery... £25.50 for 180.
The asda deals is better at 13p per nappy.. £32 for 240. I don't have an Asda near me unfortunately.
I have three children, tried every brand of nappy and have found pampers the only ones not to leak. Obviously some brands work better for others
