His idea is to get people together to bulk buy selected products in 1kg per person lots, with them taking 20% commission (so you end up with 800g). You pre-pay a set price but they will refund you if they make any further savings. You can then accept delivery and do what you will with it, or leave it with them and they will cap it up (for a fee), sell it on and split the profit with you.
Eventually there will be two sites - http://www.nootropica.org/ for the bulk buy side and http://www.nootropica.com/ for retail. At the moment only the .com is up and running (currently with the bulk buy stuff).
