JoJo, these comments are not addressed to you just thinking out loud.
IMO, I would buy flour, baking soda, cream of tartar, (
No need for baking powder) dried yeast, etc as separate items. These items are multi use items where as single use items (Pancake mix) are just that - Single use.
Now flour is tough to store for loner periods than lets say 2 years as you will leave yourself open to critters that is in all flour. Mylar bags and O2 absorbers will help but not eliminate this issue. Plus flour can go rancid although that has never happened to me.
When money is tight think about the basics. Flour and baking soda are often on sale at very reasonable prices. Also you can buy flour in 25 and 50 # bags cheap at restaurant supply businesses like Maines. Look in the yellow pages for Restaurant Supply houses in your neck of the woods.
Keep in mind that butter can be made into ghee and butter is often on sale around holidays throughout the year. I love using the slow cooker method.
Now eggs and bacon I can't help you with other than to raise chickens and pigs.
I have a friend back in RI who lives in a small town. She raises chickens with no neighbor problems as she doesn't have any roosters. She rotates her stock every spring buy buying new chicken chicks from Tractor Supply. She and her husband harvests the hens that have stopped producing. A couple of the chicks will end up being roosters and once mature or when the neighbors start to complain they get harvested too.
As written ad nauseum on UP, my neighbors and I raise pigs. One pig lasts MrsMac and I about 9 months. Total cost from bacon seed to freezer costs us just south of $2- a pound when we are done.
My whole point is when you are planning on putting things away for a rainy day, think of multi use items and if you can go back to live stock.
