My wife discovered the http://www.perfectthreads.ca web site where you can buy and sell baby clothes. It sure has been great for us as nearly everything we've been getting is practically new since many babies only wear their clothes for a short time before they outgrow them. It's been a good experience for us. Their Bargain Box is even a better deal. Having said this, we've also found great success using eBay for the same thing. You just have to watch the shipping costs.
