I clip coupons but I don't think I save that much on it. I tried a couple of those web sites where they're supposed to find all these deals for you, but unfortunately, most coupons and things featured on those sites are for highly processed junk food that we don't eat. I do save a lot of money, I think, by planning. I go to my store's web site (Publix) and check out all the deals and then I plan the week's menu from that plus what's good at the farmers' market. If the store has a good deal on, say, chicken breasts, I stock up and freeze. We love the two-for-one deals. I make kind of of a game of staying under budget and seeing how high I can get my savings on the receipt.
I used to just hand write a weekly menu, but I found the cutest menu planner in one of my son's school's fundraisers at sallyfoster.com. I post that on the fridge and not only are we saving money, but when I get home every night we avoid that whole "I don't know, what do you want" discussion.
