The cost of food is unbelievable ....shocking almost but there are ways around it. I have always couponed, before the shows and all, I have been couponing about 25 years. I buy seasonal items, and stock up on pantry items, head to the farm stands for veggie's and fruit, big box stores some items drinks, adult beverages, I grow my own herbs, and tomatoes.
One of my key things to do is meal plan, then match to sales flyers, next step check the coupons. You have to be flexible to change up things. I am a planner so with the holiday approaching I will start adding things that I know that I will be needing for the up coming season, spices, cookie and cake mixes, nuts, extra baggies, foil and foil pans. I also stock up on personal care items, so if a friend forgets, a toothbrush, toothpaste, whatever I have it on hand.
I try to make a list of events that I will need to take something for pot lucks at work, church, cookie swap parties, school events for the kids or after school activities dance class, sports, band the list can go on and on. DH's office parties, Heading to friends house for watching football, racing, celebrating whatever, Thanksgiving, Black Friday after party, Christmas parties, cocktail parties, or the big Days Thanksgiving and Christmas Eve and Day, New Years Eve and New Years Day.
Last year I got my turkey for Thanksgiving in September I used coupons, that butterball had out with a store coupon and sale price, I got my turkey for like 3dollars, It was a 9 pounder but that was perfect for my family. For Christmas I cooked just turkey thighs as my family prefers those, I also had ham but I have a few that don't like ham

I bought those in October when my store had them on sale, and I had a coupon for meat when buying other items, and a store coupon. I bought 3 package of 4 thighs each and I spent about 8 dollar, when buying special cuts or pieces the price is always higher per pound.
When using coupons use them on items you know that your going to need and items that you normally use. Otherwise your wasting money if you not going to use it. Make a list an try to stick to it, take all your coupons with you when you go, you might come across something that is a good deal and something that you use, that's when I will add in to the cart.
