I don't buy organic because I prefer local for a few reasons. The labelling of organic these days is pretty liberal. And if purchasing from a supermarket organic (which is pretty much my only option) it can still be (not always and depending on the produce) stored for longer periods before being available and that's not including transport time.

Ultimately I'd prefer to grow my own too. But in the meantime I will always support local over organic. Especially when dealing with major chains.
