I don't know the US market, but I find one in the Amazon:
http://www.amazon.com/Lakewood-Organic-PURE-Blueberry-Juice/dp/B0000ZSHBY/ref=sr_1_4?ie=UTF8&qid=1302060863&sr=8-4
It is $12.56 per bottle (about 1000ml). Is it $1.3 per day too expensive for you? I recommend you buy the frozen wild (http://www.wildblueberries.com/about_wild_blueberries/frozen.php) or organic blueberry (one cup 120 g per day). It is better to take the whole fruit than the juice.
