DunDat-
SePro, the manufacture of Sonar does not give special pricing to some dealers and not others. They are like some car dealers that this is the price and there is no other discounts.
I would check with the big chemical warehouses like Hellena Chemical, United Horticulture Prodcuts, Cygnet, ProSource One, Aquatic Control etc.
Because they purchase in quantity, they may be able to sell it at a larger discount.
