I have read on previous posts that some order ND direct from source. I have been on the ND website and cannot find any way of ordering direct - they just give a list of suppliers. The prices around here are about 65p pack so too much money for me. Can anyone advise how they order direct?

You have to telephone them, there is a number on the site, 08700 132960, this is customer services they usually can do orders.
