I can get grass-fed ground beef and ground bison at my local supermarket. I can get grass-fed lamb there as well. I can get wild-caught fish there too, when it's in season.
I get pastured eggs from a local CSA. I use them because I have a soy intollerance and chickens don't completely digest soy feed and it passes through to the eggs and meat. (And I know some sciency people who tell me that's not true, but I still have soy-intollerance reactions to the meat and eggs from regular poultry. So there!!!!) I have had to try out different poultry products because of my soy intollerance. They all say their chickens are fed a vegetarian diet. But the Rocky brand seems to be soy free. And there are a few others too.
There's a market just over an hour away from me and I like to go there to get my Thanksgiving turkey because it's completely range-fed. All their meats are grass-fed, so I will load up for the holidays.
I have ordered wild salmon online. Costco carries some wild fish and grass-fed meats. They were carrying some really good bison steaks for a bit. Wish I bought more, because when I went back to get some last weekend, they were all gone. I HATE that! I can order the same bison steaks online, but they are much more expensive. There are some canned tunas that are pole-caught. I get some shipped to me through Amazon, but saw that Costco carries them too...for now. I get wild-caught sardines too.
