Cropking doesn't sell Potassium Sulphate (0-0-50) in smaller than 50 lb. bags, but there is a source on ebay that has 5 pound bags for $13.00.
With a few math equations, a bag of the above and a bag of Mono Potassium Phosphate, one could easily make their own, very inexpensive PK boosters, in any ratio they want.
