Plan your meals around the grocery store sales. I check the sales each Wed. morning then plan my meals. This week, I got a good deal on ground turkey so we had turkey meatballs. I also found a good price on whole chickens so I made roasted chicken with carrots.
Then, you buy on sale and freeze items. My family likes tilapia. I only buy it when the "Buy 1, Get 2 Free" is running so I get three packages for the price of one. If you try to buy all your meat and produce on sale, you'll save quite a bit of money and not even have to use coupons.
