nappy question

Hi
We are expecting baby no 2. Due in January. For baby no 1 we used Huggies nappies until she was around four months. Since then we've used dry ups (much cheaper) during the day and Huggies at night.

With a new baby on the way we are keen to save some $$$ and I'm wondering if there are any other good brands out there for newborns. Or is worth sticking with Huggies?

And where is the best place to buy Huggies? Previously we bought them in big boxes from an online store but I'm wondering if it's cheaper to buy them from the supermarket when they are on special.
