Bananas are among the most popular fruit, as they are available year-round and travel well. They are also often used as a loss-leader. When I was at UCLA, the Whole Foods sold bananas at a very low price (39¢ a pound?), as a loss leader. Since I was a budget-conscious student, I would frequently just go in to buy bananas (it was 2 blocks from my apt, and on my walk home). But most shoppers who brave LA traffic to go to the grocery store would buy many other items, making the whole trip profitable for the store.
