You don't have to
be a calculator. The one I have on my wrist is perfectly adequate.
Yvonne, there's no sales tax (at least in CA, and I
think this is true nationwide) on food, except for snack/junk food. So no sales tax on meat.
I don't think of fish as "meat" either, for two reasons: fish is
pareve (neutral, neither meat nor dairy) by kosher standards; I have a number of vegetarian friends who eat (some) fish (I have vegan friends too, and have even cooked for them on occasion, but I digress).
Local prices for kosher meat (going by my freezer and my memory) include:
Ground beef, 5+ pound package: $2.59/ lb
Lean (10% fat) ground beef: $3.59
Ground (dark) turkey: $3.69
Ground lamb: $ 4.99
Ground chicken breast: $4.99
Boneless, skinless chicken thighs: $2.99
Whole chickens: $1.99
Chicken legs (bottom quarters): $1.29
Beef roasts, depending on cut: $4.99 (for example a chuck, w/ bone) - $9.99 (low fat, no-bone cuts)
Beef stew meat (no bones): $3.99
Lamb stew meat (with bones): $5.39
Lamb chops: $7.99
And I realized, I
did have lamb in the last month -- I made a stew with a mixture of beef and lamb not long ago.
