Target brand diapers cost breaks down to about $0.12 per diaper. Compare to $0.23-$0.25 per diaper and the savings adds up!
The Target I go to has them in packs of 102 for $13!! They aren't as absorbent as national brands, but I don't go through them any faster during the day. I use a more absorbent diaper at night. The savings, to my mind, is really worth it!! I've talked to some parents who've had problems with leaks, but I've not had this problem.
