I'm less hung up on "organic" than I am sticking to "happy", locally raised, and grass-fed / pastured animals. But the point is always to minimize your exposure to the crap we as a society shits into the environment every minute of every day. Sadly, eating conventionally raised animal products is the best way to consistently expose yourself to pollutants.
When I moved from capital-region NY to near Boston, MA, I was expecting my costs to go up. In grocery stores, prices have gone up in general. However, prices at the farmer's markets are still pretty much the same -- very reasonable.
I can only speak for tongue (bovine), liver (lamb, goat, chicken, bovine), and heart (bovine, lamb), as I eat them regularly and only grassfed and/or "pastured".
I find liver (esp. lamb) to be about $3/lb. Hearts, $3.50/lb. Tongue, $2/lb. All grass-fed, pastured, anti-biotic free.
I would never consider paying $10/lb for liver. Ever. A website, that ships to you, offers a premium service, so you are likely paying for that if you order online. I suggest you utilize the farms and farmers closest to you.
