Over the 16 weeks I've been Cding, I have spent about $500, I think. I was upset when I first realized that, but now I have all the prefolds I'll need forever, in infant (for next babe), and the premiums DS is in now. I have a few hyena dipes, but I bought them all used on the TP, and even most of my Medium cover stash is used Bummis. I am loving wool, so I've bought a few used covers there, too. But essentially, with the TP, I'm definately coming out ahead, especially since I'm all set for another several months, until DS outgrows M covers, and his M fitteds.
