economies of scale
Last year we got a Sam's membership around Memorial Day. I needed to buy vast quantities of meat, and there were a few things there that I knew we would use frequently. Some of our regular items include 10lb bags of frozen chicken and 6lb tubs of Peanut Butter (6 lb tub!). I shop there warily, since I know of their tendency to make things look cheap when they really aren't great deals. In fact I always leave feeling a little dirty, a little bit like I'm shopping for a used car.
Well today I needed a car battery (batteries and tires are a great way to get your money's worth at Sam's) so we made a trek down to Sam's Club. By trek, I mean a 3 mile car ride (side note: I"m spoiled by city life sometimes). Hilary was taking care of Amos (diaper+nursing) so I wandered the isles trying not to get sucked in by the 'deals'(again the comparison to used car shopping is eery). I started down the canned goods isle and passed our normal 12 pack of tomato sauce (they look like coke 12 pks) and I came across the industrial sized cans. I started looking at the 105 oz can of Tomato Sauce. We're prodigious Spaghetti eaters, and I ran a few calculations based on my sauce recipe. It turns out that we use somewhere between 1/2 and 3/4 of this beast per meal. It is even twice as cheap as the 12 pack we normally get at Sam's! Here's the rundown in table format, where the first three cans are things you find in the grocery store (sorry if the table looks funny)
can size price unit price
tiny 8oz $0.85 .106
normal 15oz $1.35 .090
large 28oz $1.80 .064
massiv 105oz $2.47 .024
that totally blows everything else out of the water!!! Here is a picture comparison of can sizes:
left to right: 6 oz can of tomato paste, 15 oz can of diced tomatoes, 105 oz can of tomato sauce

But of course if you stock up on the smaller ones when there's a sale and a coupon, you can get a normal size can for roughly $.25. :) -
yes, and Sam's isn't really about saving money since I would have to account for the fixed yearly membership cost. It is really about convenience, I don't have to scour for sales and coupons or for space to store that much food until the next time I can find the sale. -
I buy 6 massive cans of tomatoes at a time. :) Can't beat the price. -
love tomato sauce -
I, too, get the massive cans of tomato sauce...and the 12 pack...and the little ones of tomato paste. I make a sincerely massive batch of spaghetti sauce once a year (20 quarts) and use the other cans for chili and various other things. Fortunately, I have a large dry cellar to keep all my Sam's Club finds in. :) -
Oh, and heads up- Sam's is a great place to get toys in January. I know this info won't be useful for another 10 months, but still. They clearance out all the christmas toy stock in January and you can get things super cheap.
