Honestly I got them from the UK because my Danish sucks.
It is probably
cheaper due to lower VAT, but I really don't know. With increased shipping, it could even out.
I have never used fitteds but have some prefolds. I have to use nappi nippas on them before putting on pull-on pant style covers but not with wraps. The only other kinds I've used are Fuzzi Buns pocket dipes which I like a lot (got them used from a friend) and Imse Vimse AIO. I'm not as pleased with those, but I know other people love them.
