Although, lean ground beef (93/7) generally is at least a buck more per pound than fattier ground beef (80/20). I kind of suspect that is because it is harder to separate more fat out when grinding. I imagine it takes more work to get 93/7 than it does to get 80/20.
Fat is also not evenly distributed. Lots of extra fat on beef is cut from the carcass, ground, then remixed with lower fat ground beef. IIRC, 93/7 is standard, and 80/20 is just cut with fat.

ah.. so 80/20 is cheaper because it is "cut" with basically throw-away scraps. That also makes sense.
