The basics

Groceries on the cheap takes a different approach to purchasing food and getting food cooked and on the table.

Assuming we all live busy lives and have a limited amount of time to manage the get meals on the table, the approach is to spend more time planning and shopping, and less time cooking scratch food. It sounds impossible to spend less time scratch cooking, but it is entirely possible.
We call it efficient cooking.

The concept boils down to five segments.  Some are easy fixes and some will take a while.   One step at a time.   The basic concept is rather than going to a store an buying just what you need for one week, you go to the store to replenish a pantry of items you use on a regular basis.   You cook from your pantry.   The simpler the list of ingredients, the better.

1. The simplest ever. Go to multiple stores.     If you are going to one store and buying just what you need for a weeks worth of meals, the odds are against you.  The monetary odds are rigged in favor of the house just like when one would go to a casino.   Study the ads and pick 2 chain stores that have the  best prices .  This gives you the advantage of two sets of sale prices and two options for fresh produce.  Don’t overlook overstock stores or the Dollar store.  
2. Bulk buy what makes sense for your family when the cost is dramatically different.   It just makes sense to buy things you use on a daily or almost daily basis in bulk.   For us , it is oatmeal, flour, rice.  We don’t eat enough beans to use a bulk bag before they go bad. Not everything at the warehouse stores is a great buy  
3. Know your prices.  Find the rock bottom price on the things you buy on a regular basis.  Most families have a list of ten or so different meals.  List 10 -14  meals your family likes that use inexpensive sources of protein .   Make a list of shelf stable or frozen ingredients that you will use to make these dishes.   Its a project that you only have  to do once.   Now , find the RBP on these things.  Simplify.  The less things you have to buy, the less prices you have to remember.  Use a small spiral bound notebook if you need to.   (They are three in a package at the Dollar Tree). My mother used to say “ Some people could have a bargain get up and bite them in the butt,and not see it”. Don’t be that person.   When something is at a RBP. Buy as much as you can, as much as the store will allow, or as much as you need to fill in your stock, whichever comes first.  Stock a set amount of items.   Base the amount of your stock on how much you need for a particular number of meals .  Say three months, or enough to last you until you think they will go on sale again.   Its easier for me to set a particular amount of shelf space and when I see white shelf, its time to look for a sale.  The object is to NEVER PAY FULL PRICE FOR ANYTHING.  
4. Every chain store has a ‘loss leader protein” on their ad, usually on the front page.   If you buy enough  bulk ‘meat’ to last you for a month to six weeks of that meat, you will be better off.   In other words, if you eat hamburger once a week, you need enough hamburger to feed your family 4-6 times.   Simplify the cuts of meat you buy.   Pork loin, hamburger or ground turkey, chicken breasts or thighs, or whole chickens are an example.   When you get the months worth at home, portion control per meal portions, and freeze.  Butcher yourself if needed, and cook hamburger, defat, and put in portion controlled bags.  It helps if you put smaller bags in a gallon bag and label with date and description :  GB 10/17 Pick cuts that are cheaper and versatile.  
5. Waste not, want not.   Keep track of things in your refrigerator.   Use up anything that is going to expire soon.   Cookbooks on the web have search engines that will give you ideas.   
6. Learn the basics of scratch cooking—making bread, muffins, a white sauce etc.  Having the tools helps too.    Find recipes that take few ingreients and take little hands on time.  Pre-made  things cost money for others time.   There are many appliances and recipes that take little hands on time.  Pinterest is full of them.   

To sum up.  Keep a stock and replentish your stock.  Cook meals from your basic stock on hand.   This allows you to be prepared if the bleep storm happens and you can’t  get to the store.   Its piece of mind.   Waste not.   Scratch cook as much as possible.   A few things are either way too time consuming, or scratch is a lot more money than readymade.   Pasta sauce come to mind.
