A very common misconception (one that I held for quite awhile) is that you can save money with coupons, but only on junk food that you probably shouldn't be eating anyway. I was thinking about this today when I was putting away our weekly groceries. While it is quite true that you will never get a coupon for lettuce or apples, there are plenty of healthy foods that DO offer coupons.
Total pre-sale and pre-coupon value: $152
Coupon savings: $33
Today's total spent: $67
Healthy foods? Well, among other things, this trip included two packages of cheese (non-processed), 12 containers of yogurt, frozen vegetables, brown rice, and multi-grain cereal, all of which were purchased with coupons.
As for the not-so-healthy food you see in the picture, well, I certainly don't want to PAY for brownie mix, now do I? :)
