This list can change. Manufacturers occasionally add or remove products from their MAP-protected lists. We update this page when they do, but the most accurate way to confirm whether a discount applies to a specific item is to add the item to your cart and try the code at checkout. If the code doesn't work, the item is excluded. If it does work, it's eligible.
Returns On Hazardous Materials
Some of the products we sell — primarily spa and pool chemicals — are classified as hazardous materials by the U.S. Department of Transportation (DOT). These items can't be returned to us by mail, even though we'd like to make returns easy on every product. This page explains why the rule exists, what's covered, and what your options are if you have unopened chemicals you no longer need.
The short version: We can't accept hazmat returns by mail (federal regulations prohibit it), but we can accept them in person at our Idaho Falls, Boise, or Twin Falls showrooms. If a product arrived damaged or defective, that's handled differently — call us right away and we'll work with the manufacturer on a replacement or refund.

- Use a large plastic pail and dissolve 1 lb. in 5 gallons of lukewarm water, stirring with a wooden stick until the solution turns dark red and is totally dissolved.

- Stop filtration and drain all water from the filter.
- Remove elements and soak* overnight with sufficient solution to cover.
- Remove filter elements from solution; drain and rinse thoroughly with warm water until clear and replace in the filter.
