find fair trade fruit. . .where????

I have discovered that there is such a thing as fair trade fruit, specifically bananas, as well as rice and sugar. (and coffee and chocolate, which are much easier to find). Currently, when I buy bananas, I am saving an additional amount (representing the additional cost I would pay for fair trade bananas, if I could find them) and hope to donate the savings to oxfam or heifer or something similar. Does anyone know of anywhere to buy (in a local store, or online, or somehow) fair trade foods other than chocolate and coffee???
