You can probably tell from the last few posts that I'm full into Suzy Homemaker mode. Something about working at home (the writing) and saving that four hour commute brings out the nesting impulse in me. I'm all about cutting costs (at least for a couple weeks and then I'll be back to both cutting costs and increasing investing returns).
Part of saving money on food includes making good use of my pantry. When the hubby and I first looked at our house, it was the big cabinets in the kitchen that blew me away (the hubby calls it the bomb shelter as we can live for months on the canned stuff there).
However, having a pantry comes with responsibilities and that is proper food rotation. It is SO easy to simply slide the new cans of tomatoes in front of the old. Mistake. That means I'll only be using the new cans and the old cans will get very, very, very old.
It is a little more work but new product goes in the back. Because I'm lazy, that usually means I buy certain products in bulk so I only have to rotate once in a while.
I also keep an eye on best before dates and use up those items before then. Lucky for me, most cans last a long, long time (and the hubby likes to eat when we have the food). Anything in paper bags, I put in plastic.
