Kirkland Signature diaper offers your baby ultra soft comfort. The wrap-around stretch provides a secure fit for peace of mind. My daughter has wore these diapers since she was born, she is now 16 months old and I have had NO problems with diaper rash or chafing. These diaper are super absorbant. I have tried huggies an other expencive brand diapers, these are by far the best diapers and the price is right you get 184 diapers in a box and they come in 4 packs. Size 4 are 22 - 37 pounds.
The nice thing about costco is all their price are at wholesale, however you do have to have a costco membership which is $55.00 a year but being a costco member myself I truly belive that having a membership is worth it because not only can you buy these diaper but there are thousand of other items that you can buy as well.
