Query: you must be kidding!!!

while checking out pool chemicals on the web, I ran across this kemtek product on amazon.com. It is priced at $49 for a gallon of algacide/clarifier.My local lowe's store has this same product for $6.98 a gallon., No...this is not a typo.You have to be out of your mind to order this product at this obscene price.
