Grocery lists/organization binder

I may not be organized in all parts of my life but one place I am very organized is my grocery shopping lists etc. I am on a tight budget so I have found for my family that a weekly shopping trip is the best way for us. Let me explain why-

Every Monday I spend 1/2 hour making my weekly shopping list. First thing I do is set up my weekly meals. I have a sheet for that but I don't know how to link it to the blog so email me and I will send you a copy. So for each day I figure out a breakfast, lunch and dinner. For example my Monday menu for this week is cereal (only thing kids will eat), egg salad sandwiches and toss together lasagna. I will write that all down the go to the next day until I have 7 full days of meals. Then I will take out my shopping list and fill out all the ingredients and items I need to purchase to make all 7 meals and I always always include at least 1 or 2 extras of a few things (usually canned goods) to have on the shelf for food storage. My shopping list is broken up into catagories like diary, breads, baking goods, misc., meat etc. Then I will find all the coupons I can for those items for the week. I will also price check the store adds and take the ones that I need with me because walmart price matches! Yes I am one of THOSE freaks.......... I know, I know but it saves you LOTS of money on things like produce and meat because you can't always get a coupon for those. I keep my eyes out of coupon for items we use a lot. Things like yogart, milk, bread............well you get the picture. Why shop once a week you might ask? Well your fresh produce only lasts so long. I like to have fresh items around the house at all times and I just can't keep up with it when I am not shopping once a week. Also, when there is a sale on meat I will pick up more then what is on my weekly list. Maceys will have seasoned pork on sale at times 6 pieces for $3.00 or less. Drumsticks seasoned for $2.50 and lots of other great deals. Then I have a stock pile of the expensive part of a meal and the rest is simple filler. When I really keep up on this I can keep my grocery bill down to around $75 a week. Before we had Addi I was able to keep it more around $50 a week. A baby adds formula and baby food :) Ok now you read my novel. I want to hear your ideas on this. There will always be weeks when you spend more. Those weeks usually include a holiday or a special birthday dinner but if you really stick to it you will always know exactly what is for dinner and you can keep your grocery bill a lot lower. Do you have any tricks that you use to keep your grocery bill low??? Would love to hear because there is always room for improvement! Happy shopping!
