The Shopping Cart Economist has a great post on The Economics of a Watermelon.
When you have a 13-pound watermelon for $5.25, the average large variety watermelon is about 60% usable. The rest is rind weight youâ€™re paying for. That means the usable portion is about 7.8 pounds. That brings the usable portion of watermelon up to .68c per pound. The Dulcinea is about 95% usable, meaning that for a 3.5# personal melon, your rind waste is about .12 of a pound. Thatâ€™s roughly .88c per pound for usable melon.
Now that weâ€™ve taken the rind out of the equation, the price difference between the two melon types on a pound per pound basis is only about .20c difference.
She then goes on to talk about how if you bought the big watermelon but weren’t able to eat it and ended up throwing some of it away, thereby increasing the cost per pound, possibly making it cost more than the personal size watermelon (which you would pay more per ounce in the store).
So, when you’re making your grocery lists, compare more than just the cost per ounce or per unit. Think the cycle all the way through, and sometimes what intially looked to be the more expensive option turns out to be the cheapest.
If you’ve attended a workshop you know I like to say free is always cheaper. And it’s true, if you can get the smaller size for free, it’s always cheaper than even getting a larger size at 90% off, because zero always equals, well, zero.
But, that doesn’t mean that I would rather get a bunch of free samples, instead of buying a full-size product for 90% off. Thinking all the way through the equation, I’d rather use a coupon to get a 10 oz package for 50 ¢ than a 1 oz package for free, because that 10 oz package is going to last me a lot longer and is still a great deal! Do the math first, and then bring in those critical thinking skills to get the overall best deal.
Phew. Saving money is a whole lot more involved than just spending less, huh?
