Hi E.,
I dont go out of my way to look or use coupons unless I am going to buy it anyway - you can waste a lot of time and energy, looking, clipping, and driving to several stores. If this holds value for you, plan to go to one store on one shopping trip then the other the next time you go. I shop usually at HEB because of their meal deals and in store coupons for groceries. I go to a diff store for diapers on another shopping day. I took a couple days once to look and write down how much it is price per ounce (should be next to each price label on the shelf).... and found that the bulk items are cheaper than buying twice or 3 x the smaller size. Bulk is not always easier to by everything at once, if you need to - buy one bulk item at a time. Buying in bulk helps you plan better.. ie you know you use up toothpaste a tube a month, you bought 6, you should reorder 6 more 6 months from now...
Places like a Bishop's storehouse & Costco sell things in bulk. I dont use tupperware (though I like the company) and instead I use freezer bags and ziplock bags to separate... as I use or open each item.
Also I found that some items are more expensive than other places. For example same can of corn is 86cents at the grocer is sold at the dollar store for a $1. At two diff grocer stores I found my meats & frozen cheaper at one place, while canned and packaged items were cheaper by another(same brand)... by 50 cents or more! After a while you will get an idea at what works best for you.
As far as menu/ recipe ideas... My family loves pancake night. Pretty much breakfast for dinner is simple and easy. I change it up with the syrup and butter... You can put applesauce or other fruit toppings, Peanut butter... Not to mention we have more time to enjoy this meal at night then in the mornings.
Soups or crockpot dishes are also good budget dishes.. You can feed a med - large family on less than $10 a night. I also use veggies and fruits from the freezer section. Its healthier than canned items and you dont have to worry about throwing food away because you didnt use it before it went bad.
Also milk is pretty expensive if you don't get WIC. Look for mixes that dont need milk and can be completed by using water. Or try using powder milk in your mix recipes.
Generic brands (like HEB) are similar to brand names but cheaper (I do buy one or two things brand named because of the taste)and can make a big difference.
I also looked at the snacks I was buying for my kids. This ended up being a large chunk of change! So I switched to popcorn, cookie mixes, jello mixes, apples, oranges, and carrot sticks. (I dont buy that all on one shopping trip or they would eat it all in one week) It ends up being healthier for them and my budget too.
When cooking try to make 2x as much. Then before serving the dinner put half away and put it in the fridge or freezer. This will help out with the energy bill as this become more of a habit.
Also look at the distance of your grocery store. If you end up driving 30 min for savings... how much did you spend in gas? Usually this ends up costing as much as going to a local grocer store. You could also look into online stores - some will ship free after a min purchase. Angel food ministries are for everyone and are good budget savers. Dream Dinners is good if you want to premake or preplan gourmet meals.
I think a menu plan was mentioned - Its a great idea! It will help you not purchase groceries that will sit around and go bad...
Hope this helps! Let us know what you decided to do!
