My savings goes in waves, based on my stockpile. I was very serious about building up (and donating) last year between Jan-June, savings was usually around 40%, but I was building a full stockpile. Then in June-September we had a number of major family changes (moving, selling a business, college, surgeries, emergencies, everyone is fine now but it was hairy for a while!) and fortunately I had a full stockpile to rely on and I don't think I even spent $10 a week buying very little fresh food and feeding 4 people and still making donations! It was a huge load off my mind to be provided for by good planning. I had the emergency food, toothpaste, paper towels, laundry detergent, everything when I needed it most. By November I had depleted a good bit of the stockpile and I started barely picking up again on shopping, and just last month had to get serious again. Anyway I would suggest use the matchups on couponmom.com and plan, spend when you can, then when things get weird or get crazy you can rely on your planning and stockpile to carry you through until things get better. You'll still spend the same at first, but you'll GET more for the same amount of money, and that will come in handy later. For me I had several months where I spent almost nothing on grocery and drugstore stuff, thank goodness I had planned ahead when I did.
