Milk is quickly turning into liquid gold for one Washington dairy farm during a time when most in the industry are barely making ends meet. 

The farm's key to success: dairy-loving Canadians eager to drive the distance to save a few dollars on milk.

While it’s not unusual for Canadians to cross into the U.S. for grocery products, a stronger Canadian dollar has combined with the popularity of milk to create the "udderly perfect" situation for Washington stores and dairies.

Edaleen Dairy, located near Lynden, Wash., opened a new shop in Sumas last year, conveniently located just minutes away from the border. The store was strategically placed to cash in on Canadian customers looking for milk at bargain prices, general manager Mitch Moorlag told The Vancouver Sun in this article.

Milk is tax-exempt in Washington, and one gallon of non-fat milk retails for CA$3 at the Edaleen Dairy, nearly half what a similar-sized jug costs at a Canadian supermarket.

The Canada Border Services Agency’s policy on dairy imports reports that a single shopper can bring up to 44 pounds of dairy products worth CA$20 or less in Canada per trip. A buyer can purchase six, one-gallon jugs of non-fat milk from the dairy for around CA$17 without having to pay extra duties at the border.  The same purchase in Canada would cost nearly double that, adding up to CA$30, according to The Vancouver Sun.
