look out for Ecostore, Planet Aware and Euca.
Just thought i'd add my 2 bobs worth...XD
I use Ecostore because I get itchy from normal washing powder and it's devine. It has a really soft light smell and the clothes smell so yummy when you hang them out to dry.
Good to know you can use it for MCN's! Now I don't have to track down something else!

Just on a completely different topic... does anyone use the GAIA baby moisturisers and stuff? I noticed my supermarket sells it and I was quite surprised!
