Based on the ingredient list, most of it is offal- beef parts that aren’t highly desired. Grass fed beef especially doesn’t have a huge market here, and the organ meats in the, are very likely unused. My grocery stores only have the most popular of cuts, and part of the reason grass fed beef is so expensive is because less of it gets used. I get less than 10 requests a year for grass fed beef,and when I get it, it’s usually sirloin or tenderloin. That’s alot of unused beef
I don’t know if all these things are the answer to your question, but it may play a part.
