I have a family of three, myself, my husband and my two year old daughter. I spend about $125 a week, more or less some weeks. This is also with Wic giving me 5 gallons of milk, 36 eggs, 5 cans of juice, two pounds of cheese, 2 boxes of cereal, a jar of peanut butter, and a $5 check towards fruits and veggies every month. I do buy some processed foods, i try not to buy too many but some nights I need dinner in a snap ya know. I do save some money shopping aldi's for paper products, and a few other things(I don't trust all of the foreign brands on some items). I do buy a lot of wegmans brand products (Cheese, pastas, bread, canned and frozen fruits and veggies) but I also have to buy certain brands with some things. I always found coupons to be a waste of time, they dont necessarily go along with the sales and I find myself picking something up just because I have a coupon that i really dont need. Fresh Fruits such as bananas and grapes are a staple in my house, the rest i genaerally do canned unless they are in season and really good fresh. Meats range from skinless boneless ckn breast, to 95% lean ground beef, ground turkey, soy burgers, pork chops, haddock and the occasonal splurge on seafood night.
I try not to eat out too much, maybe twice a month, which saves money, this will generally be Pier 57, Red lobster, kirby's, or the once a month trip to McDonald's(I know it's bad I can't help it LOL,)
I also stay at home primarily and I like to make mostly everything from scratch, no jarred sauces(Tomato, alfredo, cheese), no supper in a box type entrees.
The biggest money saver to me is to sit down Sunday mornings and look at the sales then plan you whole weeks worth of meals around what's on sale. Also taste of Homes has many money saving dinner recipes, and i have a few of my own, i'd be happy to share just send me a message.
Also....this was an interesting question, Thanks for posting it, I will certainly keep up with people's responses!
