Goof for you. I like water, tea, you name it, but I love coffee. I figure it may keep 5 years properly sealed in a freezer. I have never had bad coffee yet and I think some of it was 3-4 years old and not stored all that well.I have never drank a full cup of coffee (combined) in my life. No reason. Just haven't wanted to. . I do drink unsweetened tea, but I'm a water person.
I saw some powdered milk today at a local save a lot that was sealed in a can, it was Nestle Nido 26.6 cents per ounce, I have never seen this brand here before, don't know if the price is good or not. I also found some boxed milk at dollar tree, it sits on the shelf and is good for one year, 2% one quart$1.00. I bought two to try, it tastes just like fresh milk.
I have a record book, it is a tiny notebook with sections divided for canned, drinks, etc. I write prices in, when I see a great price, I buy. May start a thread on how this works.
