Go to Sam's club and look for the red "reduced price" stickers on their meat packages; morning right after they open is the best time. For USDA "Choice" tenderloin (filet mignon) they knock $3 off the price per pound which last time was $12 instead of $15.  The packages are around 2 3/4 pounds and there are four filets in them.  Three are 10 ounces plus and one is a "tail" cut of around 6 ounces.  Cook one and freeze the rest.  I get about seven or eight meals per package, paired with baked tater, corn on the cob, rice, whatever veggie is on sale. For around $5 per meal plus sides that's a relatively inexpensive quality steak dinner.
