Bum Covered Diapers has a great new deal going on fitted diapers. They're offering a starting prices of $5 for one of their "build-your-own" fitted diapers. They don't have too much selection on different materials, but enough to make it worthwhile considering the price, and they do have a good amount of different prints available. I have a feeling that the price will eventually go up, though, since they mentioned that they're still in the process of perfecting their patterns which is the reason for the low, low price.
I managed to buy one of their diapers today for only the cost of shipping and would have posted how to do so here, but it expired at noon today and I couldn't get to a computer by then. :-( I'm so sorry!
However, you still may be able to try one of these diapers for free. Check out the details here.
