I never buy bananas, avocado, mangos, garlic, oranges or onions organic. Stuff like lettuce/spinach leaves, red/green pepper, carrots and apples etc yes I do buy organic. Anything you peel and eat, there's no point buying them organic. The prices are too g-d high.
I don't buy farmed salmon etc. I do buy fish from a local fishery once or twice a month. And I don't eat meat much... at the most I'll have chicken twice a month. Those I do buy organic.
I've let milk and dairy go. Instead, I buy organic almond milk. I do love yogurt so I'll buy that organic eveyr once in a while. But I've actually made yogurt out of almond milk. It's delicious!
