I got 16 used pocket diapers for $40- craigslist
And another 7 used pocket diapers for $12-fb page called cloth diaper swap
They were in brand new used condition and I don't have to buy a special laundry detergent I mean I would if my child had a problem with the cheap stuff but he doesn't. I have enough diapers that I can go 2-3 days betweenwashes .
I guess not everyone is comfortable with used but there are co-ops that you can get into then you can get brand new diapers for used prices... However it could take a month or so to get.
Just like anything in life do it right and look for a good deal.
