Frugal Living NW has the scoop on how to get "Comforts for Baby" Kroger brand diapers for $3.99 a pack right here. I've never used this brand, but I'd imagine they work just fine for daytime.
We're about out of disposables, so both boys will be going back into cloth. I had stockpiled quite a bit more diapers than I realized in an effort to make things easier on me following the birth of the youngest (he's 5 months!). Cloth are so much cheaper in the long run, but disposables are nice to have on hand sometimes.
