It seems that in this life you either have to spend money or spend time. It's rare that you can save both at the same time.
I've got the same story as the ones posted above, I used to be able to save with coupons, especially when stores offered to double them. But now I buy mostly staples and store brands, and don't find enough worthwhile coupons to make it worth my time & effort to collect them.
It's certainly not worth it to make special trips to different stores to save small amounts on items, but I do pay attention to where the best prices are for the things I use the most, and try to buy them there. Most of the stores are in the same part of town, and I am usually somewhere in the area at some time during the week, so it's fairly easy to stop in more than one place if needed.
My 2 best tools for saving $ are a pocket memo book and a small calculator. The memo book is lettered A-Z and I can jot prices in there for items I use the most when I am in different stores. I don't make it a big research project, just make notes now & again, especially for higher priced things or things we use the most. I find that I can often remember "the price to beat" and keep it in mind. I do most of our shopping at our area grocery chain, Publix. They have fanTAStic weekly sales, a lot of BOGOs, and I stock up on the things we need when they go on sale like that. Walgreens also has great weekly sales and there is one in the same shopping strip as our Publix. Otherwise, a lot of the things we use are priced best at
WalMart This area has some good dollar stores where I buy certain things. We have a membership to Sam's Club because they stock a lot of their store brand of staples, such as big blocks of cheddar cheese & boxes of powdered milk.
I use the calculator to check & compare unit prices. Not everything is priced best at the warehouse clubs or dollar stores. Here's an easy way to compare prices -- take the price of Item A and divide it by its units -- the answer is the unit price of Item A. Now multiply Item A's unit price by the number of units of Item B. Compare the answer to the actual price of Item B. If that answer is lower than Item B's price, then A is the better deal. If it's higher, then buy B. This way you also see just how much the difference is in the two items, and if it's really worth it to buy the cheaper one. If you're only saving a few cents it may not be worth it to buy a larger container or a lesser quality of something.
Here in South Florida we have to stock up on non-perishables for hurricane season. I start in the spring, adding a few cans & boxes each shopping trip, and mark them with an H/year. They may not be used unless we've had a hurricane or until that year's season has officially ended.
