Maybe enough people grow citrus at home there is not enough retail market. I quit buying orange juice once it got above 3 or 4$ a gallon. We still buy the mandarin oranges rom the store but are working towards never having to buy those again either. What amazes me when i drive around here is how much water and resources are spent on trees that don't produce fruit. Imagine how cheap fresh fruit would be if all these business parks etc were growing fruit trees instead of ornamentals. It doesnt make much sense really. Especially in CA where all the trees need irrigation.
