I'm really stretching it a little to try to devote an entire blog post to cheap sources for cloth diapers. Here's the list, in descending order of price:
There are a veritable multitude of work-at-home moms making bucks on the side selling diapers on Etsy. Prices range from around $10 (or $6 on sale) to off the charts for super-cute styles, or custom designs. We bought Jude's cloth pull-ups from this shop. Although it seems like she's no longer selling the style we bought.
This is a small-time distribution website for natural parenting resources. The reason they work for me is Swagbucks! A 5$ gift card is only 350 swagbucks and two will get you their signature organic bamboo pre-fold and cover-- you pay about $5 shipping. Sweet deal!
3) Amazon clearance
The regular, everyday price on Amazon really aren't any better than buying direct, and they don't have a huge selection, BUT! If you collect Swagbucks for Amazon gift cards, or you find a good clearance sale, you can really get a great deal! We bought our cloth swim diapers there for about $8 a pair and got free shipping.
I buy on Ebay and Craigslist most often. They are the best dependable deals I've found. Ebay always has pockets for around $5-- shipping included (Hong Kong knock-offs of Fuzzi Bunz). Occasionally I"ll find someone selling extras off their stash with low shipping, too.
Craigslist is my BFF. Seriously. Even before I started actually USING cloth with Jamie I ran across a few people clearing out their stashes when they potty-trained their youngest child. I've gotten diapers with plenty of wear left for as little as a buck or two a piece. I bought all my shaped/contoured diapers off a woman for $2 each. It was awesome. I got wool and fleece covers for about $8 each.
Yardsales with cloth diapers are like the Holy Grail for this Cheap Mama. The problem is, of course, you can't often find diapers at yard sales. Most people (as do I) try to make a little back on their investment when they sell off their stashes, so they list them on Ebay or CL for other people specifically looking for cloth diapers to find. But, oh mama! when you can find one! My fav story is some old (reeeeally old) Fuzzi Bunz I bought for $4 each. They worked great for the four months or so that they fit Jamie, despite their age, never leaking-- not once. And THEN. I sold them. For $5 each!!!!!!!!!!! On Craigslist :)
Now THAT'S a Cheap Mama Moment.
