That's sort of a generic title to the post, which I could be using for a fair number of mine.
Anyhow, I'm a coffee drinker, though over the years I've dropped from maybe 10 cups of regular down to one Starbucks vente regular used to spike maybe 6 cups of decaf. The point is, since I started at ASCS I was involved with the office coffee pot, that indispensable support for most bureaucrats. I can remember when a 3-lb can of coffee was about $3. Then I remember when they went to "flaked" coffee, which reduced the weight without changing the size of the can. Think that was about 33 oz. But I noticed this morning, when I opened a new can, it was only about 2/3 full and the weight was down to 22 oz. (for about $8).
The logic is that existing supply chains are set up to package, ship, and store the old 3 lb container, so changing the container size doesn't make sense when the price changes, and maybe the customer won't notice the price increase when it's achieved by reducing the quantity, but there must be some point where saving the cost of shipping air (the empty space in the can) around the country makes a change worthwhile. Isn't there?
