I have posted some of this before in other post... Everything is kinda like a puzzle you have to have all the piece's to get a clear picture...
1) Well stocked pantry - pack your pantry with items that you use constantly, how your family eats, and what you all like to eat.
2) Dietary restrictions - items that you can use and keep on hand for whoever in your family has them.
3) Check out the grocery flyers and Ad's - divided by stores write down or circle the flyer.
4) Limit trips to the Store - this is the biggest savings thing..
5) Start a list, divide the list up - however you want- household, produce, meat, however makes things work for you. I have a list on the side of the fridge, and I write down what I run out of,
6) Plan where you are shopping at
Next step - Before you get in the car -
1) Meal planning... you can be as detailed as you want, or go with something more casual
2) Know what you are going to do with left overs - are they for lunches, or to make side dishes,
3) Just because something is a good deal if you don't have any idea what to do with it, and it sits and goes to waste. Big hit to the budget.
4) Inventory the pantry, on what needs to be replaced
5) Make the list - I write it down old school and then take it with you... don't forget a pen or pencil to mark it off...
In the store -
1) Do not go hungry to the grocery store...
2) Try if possible to go alone it's easier to focus on what you are doing... If this is something that you can't do, then tell the kiddo's that they can each get a treat if they are good... if they are old enough have them mark thing off the list...
3) Stick to the list - with that said some times there will be in store specials - again if it a really great price, I ask myself what are you going to make with it?
You have to find what works for you... and your family...
