The L/S has always been available in 5 gallon buckets, some that resell it under various names ask $50 for a 8 oz bottle.................so when you buy 4 of my 16oz bottles retail for $140, it seems very cheap....and when you buy 25 bottles 16oz for $625 it is cheaper yet and 5 gallons for $800 cheapest of all.
Often those buying by the case of 25 double their $$$ and they never had to make anything!!!!!!!!!! So the reseller always makes the most profits!
