Here is the article.
Stockpiling has saved me a TON of money. If you don't do it...give it a try. Just find a corner to pile your stuff and start watching the sales. Shelves are nice but not necessary. I remember reading in the Tightwad Gazette once...Would you rent out the space under your bed for $30 a month? Who wouldn't? Well, if you put food under there that you got a great deal on that is essentially what you are doing. Most of us here in WI are fortunate enough to have basements so maybe you won't even have to put a bunch of stuff under your bed!
Think you don't have room in your budget to stockpile? Think again. The little bit you save this week can be used to save more next week....until you rarely pay full price for the things you use the most. (Like rolling ECBs!) If you already stockpile a little bit (toothpaste anyone?), branch out to other products to save even more.
I've talked about this before but since this is a good time of year to buy certain sale items I thought it might be a good reminder. Keep an eye out for sales on baking supplies, spices, and turkeys(!) in the next few weeks. Buy enough to last you until next year at this time. You'll love pulling out items instead of adding them to your shopping list. And come this time next year if prices have gone up (and they will!) you be using items bought at this year's (lower) prices!
Below is a picture of some of my current stockpile. I didn't pay full price for any of these items and some I got for free.
