i like Baby Earth. They have a website- babyearth.com. I think I mainly just like them because they are 20 minutes away from my house, they have a pretty decent selection, and I can actually see & touch the diapers and talk to the salesperson about them. Also I once got a free pair of super cute baby legwarmers from them with the purchase of a diaper and that was nice.
ok my new fav is
www.tinybirdsorganics.com a local store & she offers free shipping! lots of organic diapers to choose from!
