I just look for what’s on sale. The “Managers Special” section often has something good and at a decent price. Sometimes there are loss-leader type sales. Bought some ground beef for $1.49/lb a few months ago that I have to think was a loss-leader since it was advertised.
I’m not a fan of ground beef in a “tube” but that’s typically one of the cheapest and fattiest of the ground meats in the store. I much prefer the ground in the blister packs that I can see the actual meat, not a picture of it printed on the tube. Texture is different, at least to me.
FWIW, I often take sous vide chuck or shoulder type roasts to 3 days. I know some people probably think that’s too long but I like them fork tender with no need of a knife to eat. (I do use a knife to slice it.) Had one over the weekend with company over and they said it was the best they’ve ever had. (They wanted to know what the sous vide was so… we had to demonstrate… and how do you demonstrate without a sample?
We have a bit of a collection in the freezer of various meats, chicken legs, chicken thighs, chicken breasts, ground chuck, ground beef, shoulder roasts, chuck roasts… we don’t usually go to the store with anything in particular in mind but often come across a bargain of some kind. And when we don’t, it’s not a big deal since we have a pretty good collection in the freezer already.
My best find to date was a 1 pound pack of ground lamb for $0.99. It’s usually like $9/lb where I bought it. I was in the right place at the right time.
