It used to be that Trader Joe's did not always carry the same items week-to-week. Something you really liked would disappear from the shelves never to be seen again. This still happens with some things. But that was one way they kept prices down in the past. Good deals on stuff that wouldn't always be there. Nowadays they are much larger so they can get good deals on things that will be around for a while because they can sell a lot of it. In other words, the prices are different based on normal retail pricing methods and not because there are special levels of organic (although Whole Foods kind of made up their own levels for some things.)
