I bought the huge packs from Sam's Club, one in each size, just to see how we like them, so we probably won't buy more until and unless we need them. I bought a box of the 1-2s and a box of the 3s. The smaller ones came 216 in a box for $34, and the 3s came 160 to a box for the same amount. We also bought a giant box of wipes too, and I have a few packages of newborns.
