Beef from safeway (chuck roast/steak or top round): $1.50-$1.99/lb
Eggs: $2.50-$3 / 18
Cheese: $3-4 a pound.
Butter: $2.09 a pound

I buy about 12 pounds of beef, some butter, a few eggs, and occasionally some cheese. I rarely have a weekly grocery bill over $40, and most of the time it's around $30.

I've been eating like this for about six months. I have no weight-loss goals; I'm just looking to get stronger and stay healthy, and it works great.
