As frugal as I am, you may be surprised to find out that I don't mind spending considerable money on healthy food, if that is what it takes. Like Connie, I buy a lot of fresh produce, meat, chicken, fish, and shellfish, and like Goonie, I only use coupons on something I would buy even without a coupon. But I seldom if ever tell myself that I cannot afford some type of healthy food. I probably spend more on groceries just for myself, than do most entire families here.
Anyway, I usually only have a few coupons (if any) and I keep them in my wallet. Just before checking out, I get out my wallet and check the coupons to see if I happened to have any of those things in my basket. Usually I don't. Most of my coupons end up going in the trash after they expire, but I still look for coupons and pick out the ones I might use.
When I retire in a couple of years, I will probably need to work on reducing my food costs. I do plan to start a vegetable garden, for health more than for the savings, actually. I really do enjoy fresh vegetables, and vegetables right out of the garden are so healthy.
