Organic food tips

I like the idea of buying foods in season, as they do appear cheaper and a lot tastier. I am also getting into buying more local produce and trying, where possible, to buy the organic food (which is definitely not cheaper). I am however, fairly often, baffled by some of the jargon that appears on organic packaging. Has enyone managed to work out what this actualy means? Or, does anyone have any specific tips on eating organic foods vs. non-organic foods?

What do you think?
