Affiliate disclosure
Some links on this site are affiliate links, including Amazon Associates links. If you buy through one we may earn a commission at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. Stores without an affiliate programme are listed all the same, and commissions never affect ranking: the tables sort on price per pound of chlorine alone.
How these prices are collected
119 products are tracked from each store's own public product page. Every row shows the date its price was last collected. Amazon prices are fetched live when the page loads and are never stored. Liquid chlorine is hazardous to ship, so many stores sell it for in-store pickup only; those rows are marked. Prices change without notice and in-store prices vary by location, so confirm on the store's page before buying.
