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.
A handful of brands and products on our site can't be discounted with promo codes (including the WELCOME code) or other Leisure Time Inc. discounts. We know this can be disappointing if you've spotted something you wanted to save on — but the rule isn't ours to bend. Manufacturers set these restrictions, and authorized dealers like LTI are required to follow them.
This page lists every excluded brand and product so you can check before checkout, and explains why these restrictions exist in the first place.
The short version: Manufacturers — not LTI — decide which products can and can't be discounted. The brands and products on this page are protected under manufacturer pricing policies. They go on sale during manufacturer-authorized promotions, but they aren't eligible for general discount codes.
Sundance® Spas 6541-397S Complete Filter Series 880
Overview
Replacement filter for your Sundance® Spa. This spa filter is the industry’s first interlocking system to provide dual filtration, which produces the purest water. The outer filter traps large particles while the inner filter traps ultra-fine particles. You can wash out the first-stage filter to save on replacement spa filters.
