My DF used seconds for his daughter and said they were good but you did have to chuck a few out
I've rarely had to chuck a dud nappy out from Naelfran, maybe they have changed their standards a bit since then? It definitely works out way cheaper than even Aldi, but Aldi are still sensational for their price.

Definitely don't go nuts buying nappies just yet. You may not like that particular type once bub is here and you'll be stuck with a whole stack you don't want to use! I was given a whole box of Huggies newborn nappies when DS2 was born, but he was too big for them! I ended up passing them on to someone else.
