gDiapers -- nice ad copy, but whoa.
gDiaper liner refills (diapers.com):
==> 128 / 52.00 = 41 cents each
==> 258 / $39.99 = 15.5 cents each
P.S. By a quick calculation similar to this one (we don't fit 24 diapers in one load, but we have a much more efficient washer than he does, etc...) or this one . . . I figure that each cloth diaper costs us something like 6-12 cents of energy & detergent, plus the sunk cost of the washer & dryer & the diapers. Plus labor.
