'Cheap organic' is an oxymoron LOL.
While it'd be ideal to eat all organic, for most of us it's not possible because of the price and availability.
I buy organic greens and some organic fruits from Whole Foods, but the bulk of my fruit is conventional from Costco.
If I were you I'd get a membership at Costco and buy in bulk every 2 weeks. The closest one for you is about 20 miles in Canada witch is not to bad, but I don't know crossing the border back and forth how time consuming or inconvenient is..?
