Absolutely! I do this as wellThe "manager's mark down" tags in the meat case are our deep freeze's best friends.
There's just the two of us, but we've been known to buy the HUGE packages of chicken parts, pork roasts, ground beef, or whatever, and divide it up into more reasonable size packages in zipper freezer bags, and put them in the deep freeze at -10 F (-23C).
Also, I have no problem buying the "primal cuts" of beef and pork and doing a little home butchering myself.
I've seen whole pork loins at over two dollars a pound less than a package of pork chops. Yes, I'm buying nine or ten pounds of meat, but do you know how many meals we'll get out of that?
