I've got some Sleep Powders for sale with Zoltan at Fort Buda deed, Independance (50x,7y on community map).
10 sleep powders on hand with the option open for you to buy a total of 30 sleep powders.
1.2 silver coins each for my delivering to a coastal location in the Southern Freedom Isles (except no deliveries to Chaos).
1.1 silver coins each if you wish to pick them up (my deed, Fort Buda on the catseye highways, has a port to meet at).
Addendum: PM me here (Tristanc on forum) to arrange any deals.
