Google search for [diapers]. 128 Pampers for $35 from Google Shopping Express ($0.27/ct), 88 Pampers for $25 from Target ($0.28/ct), 144 Pampers for $31 from Walmart ($0.21/ct). Other brands do get a fair bit cheaper - 140 Huggies for $21 from Target ($0.13/ct), 256 Luvs for $27 from Target ($0.10/ct), and we just tried buying some store-brand Target diapers that are 40% of the cost of Pampers. We're fairly brand-loyal as diapers go, though, because we've found that the Huggies blow out a lot more than Pampers (at least on our kid, who is pretty thin) and the Targets aren't nearly as absorbent.
