    Price Match Policy Terms and Conditions

    Effective November 3, 2025

    To Qualify for a Price Match:

    • The Sauna Republic product must be new and identical (i.e., same brand, including model number and color), in-stock at the competitor, and available for delivery at the time of purchase.
    • We will price match only online dealers; no brick and mortar stores. Competitors must be online retailers that are shipped from and sold by an authorized online retailer and subject to the terms, conditions, and exclusions referenced herein.

    • One Price Match permissible per identical item, per customer, at the current pre-tax price is available.

    How to Request a Price Match

    The quickest way to request a price match is to call us, email us, or use our live chat. Direct your Sales Support agent to the competitor's website with the lower price or provide them with a legitimate quote.

    • Clearance, discontinued products, closeout sales, refurbished, and open-box items are excluded.

    Disclaimer

    The Sauna Republic reserves the right to restrict or exclude items that have been subject to fraud, tampering, editing, misrepresentation, or based upon price errors. We will always work to provide the lowest available price for products. This policy is subject to change without notice.

    Frequently Asked Price Match Questions (FAQ)

    What qualifies as proof of a price when requesting a price match?

    If you have the competitor's advertisement, present the entire printed ad or a photocopy of the ad. Digital versions of printed advertisements are accepted. If you find the price online, please present a link to the price from an authorized seller. A sales associate will then verify the match.

    Will the total retail price of the competitor item be matched?

    Yes. Price match will take into account any hidden costs of the item like shipping and delivery fees. For example, if a competitor is offering an item at $5,000 plus $950 shipping, the match price will be $5,950. Our sales associate will calculate the final cost of the competitor item including shipping and delivery fees.

    Do items from warehouse clubs like Sam's or Costco qualify for price match?

    Warehouse clubs like Sam's and Costco can often offer lower prices through fee-based memberships that we cannot price match. We reserve the right to decline price matches from retailers requiring paid membership access.

    Does an item have to be in stock to receive a price match?

    Competitor items must be in stock on the competitor's website at the time a price match is requested.

    What constitutes advertising/pricing errors on the part of a competitor item?

    Many manufacturers have strict rules about the minimum price that an item can be advertised for (MAP). Retailers that advertise or sell products for lower than these prices are violating the rules of these manufacturers. We may or may not be allowed to match a price violation, depending on the manufacturer's stance. The best way to find out if a price can be matched is to contact us so an associate can verify the information and policy.

    We currently offer financing options through ShopPay.
