I don't stop buying nappies.
I love pretty nappies. Itti's, D&F, HL, WN, a few good staples TB fitted's, Wonderoo's, pumpkin pants ect I do think once you find a site you do go back time and again.
I just found Baba moo don't know if she does wholesell but I love her stuff. Oh and Rufflebums took me months to get a slot.
Sorry I've just thrown my favourite nappy brands at you.
Good luck though.
