Around .14 per dipe, depending on size and package size. It wasn't worth it to me since I could often pay .15 for Pampers with coupons and deal or Amazon. I hated the Target diapers but many love them!
I get coupons from the register for them a lot. Usually $1 off any box- with a sale I wanna say 13cents per size 3, 2 weeks ago. I used to buy them for Justin and once and awhile I'll get them for B. They only come in blue and green dots. When they make girl color dots, I'll buy them for my Nat.
I love them and they are usually the only diapers I buy. (Unless Wegmans is running a coupon, like they are now.) Sometimes the Target website has a printable coupon for $1 off, and like MrsW said- they always give me one at the register whenever I buy diapers.
Re: Target diapers
We never tried them, but this made me laugh!
