So do they discount for water content?

Pity the factories don't have a setup to buy direct with say a minimum 250 kilo?
Our farm gate buyer gave us 19bt/kilo yesterday minus discount 8% water content guesstimate..think he sells to another middle man as he is small time....real convenient that he picks up from our farm though.
Hear that some middleman buyers are paying 17-18bt and discounting as much as 15%.
