“Shop in stores with concrete floors.”
A self-made millionaire gave me that little nugget of wisdom. And boy oh boy, he was dead on the money. Basically, those huge warehouse stores (like Costco, Sam’s Club, and BJ's) are a treasure trove of cheap deals for the frugal shopper.
Now, I’m not suggesting everything they sell is quite right for your needs. A five-gallon drum of relish is probably going to go bad long before I get to use even half of it. But when it comes to things like toilet paper, cling wrap, aluminum foil, freezer goods, meats, anything like that, you’re getting a steal. I bought an industrial size roll of aluminum foil two years ago, and it’s still looking like it could last another two years.
Admittedly, the big stores are members-only places, and usually you pay anywhere from $30-$100 per year for the right to shop there. But you’ll make that back on your first big shop. I know I did. And on some of the larger electronic items, furniture, fridges, washers and driers, well, the price of admission is worth it to get that huge discount on one big purchase.

If you’re still not convinced, go by your local warehouse store and see the deals for yourself. Most of them will give you a pass to go and look around for free. Some even give you a one-day special, allowing you to buy whatever you want without paying the membership fee. But trust me, you’ll find way too many low prices to ever think about shopping at a regular grocery store again. (See also: 16 Tips to Shopping Warehouse Stores)
