If you're looking for retail locations to buy Adblue aka Diesel Exhaust Fluid (DEF) below is a link to the Detroit Diesel (owned by Daimler) Website where they have a locator. There are over 2500 locations in the US stocking DEF according to the website.

I've also been told that most VW dealers have the 2.5 gallon size at a lower price than this one.

I ordered mine at Napa Auto Parts, $11.99 per 2.5 gal. You have to order it via store though.
