Yes... sass is more difficult to get,thanks to our not so friendly southern neighbours,and the regulations started changing in January 2003.Dope is right that one can find it in small quantities,just have to look.
P heard from a supplier the regulations allow 4 kg a month,and that the regulations were going to be loosening up,and the prices dropping in the summer;but look to pay $100 to 125 a kilo....but that's irrelavent.Good luck.
