Gah, what do they say. I have to think now, I haven't finished my first cup of coffee The store tag on the shelf says diaper service quality, but I think the package says something about them being premium diapers.
The cheep ones sell in a pack of 12 for $10, and will say super absorbant poly-fill,
The good ones are 6 for $12. That is one way to tell the difference. They are a smaller package and more money. Also the cheep ones will have that weave (birdeye) feeling, and the good ones will be more cottony feeling. I wish I had a package here at the house, but It has been months since buying some.
I hope that makes sense.
