I love to buy local. I think capitalism is a wonderful thing, and I love it when people begin a business based on a dream, and they make a living doing that business. In Tulsa, there are two places that are great for organic and natural supplies, support and classes. Ludeby's Ecobaby (www.lundebys.com) on Brookside is one of my favs. As soon as you walk in the store, you're nostrils are flooded with the smell of wood. Ah, fresh wood. I love it! Ludeby's is great for supplies once you've had your baby all they way through toddlers. Another fav of mine is Natural Lullabies. This store is really good for pregnancy through birth. The classes they offer is what sets them apart. We took their childbirth classes and loved them. We also used a doula, Angela James, from there, and I couldn't have made it through birth without her. I HIGHLY recommend a doula for birth if you're choosing to go without drugs. I have an extremely supportive husband who was absolutely fabulous during the entire birthing process, but I still couldn't have made it without Angela. All this to say, I got all of my cloth diaper stuff from these two stores.
If you're looking to save money on cloth diapers, then I highly recommend checking out craigslist and ebay first. Some will sell used diapers. . .which I tend to shy away from, but many will sell new ones for bargain prices. As I said before, try a little of everything to start with and see what works best for you.
