California -Based businesses must pay sales tax to the state on product sales in California, and generally pass that cost on to their customers. At www.alfresco-heating.com, if you use the coupon code NOTAX at checkout, you won't pay the sales tax, on your purchase of over $250. We will pay the tax!

If you are in any of the United States other than California, we won't charge you sales tax anyway - no coupon needed.
