FJ I think you should email about the snaps on the sandman nappy. If they are faulty then it should be replaced and the WAHM should know about it so she can rectify the situation.

Michelle sus out the cost of wetbags before buying your PUL. They are about $15 - 20ish depending on what you're after. Unless you're going to get into making nappies as well then the cost of buying PUL for just a wet bag may not be economical IYKWIM.

That's just my opinion though
