      Manufacturer’s Pricing Policy

      Why do I need to contact you in order to place my order?

      As an authorized dealer for the product you are looking at, is bound by certain agreements with our manufacturer partners in how we display, price and sell certain products.

      Some items may not be able to be advertised below a certain price or any pricing at all and others may not be able to be added to a shopping cart via an “add to cart” button.

      If a competitor’s website has the same product but is not restricting the display/functionality in the same way that you see here on, than that competitor is likely NOT an authorized dealer.

      What does that mean for you as the customer? It is very likely that the manufacturer may not honor your products warranty, or that your product was never intended for the US market to begin with.

      If you have any questions regarding a specific product, please do not hesitate to contact us at (888) 392-4814.
