That may well be true, but it still doesn't make the analogy any less flawed. The cigarette purchases depend on notions of stockpiling that just don't work in the context of CDs, because using a CD doesn't deplete your stock.
An analogy, by definition, compares dissimilar things. To elements only have to be comparable in one dimension to serve in an analogy. If you like Reiner's work with the CSO, you could buy each of 60 cds over the next few years for $17 a pop, or you could have bought the box for $100. It's cheaper to bulk purchase this kind of consumer good rather than drag it out with expensive individual purchases. That's a mathematical fact which is also true of buying cigarettes in bulk. If I buy a pack of cigarettes, I will smoke them all and later buy more. If I buy a box of CDs I will listen to them all and eventually buy more. If you want to argue that there is no box you would want to listen to or own more than 10 discs of, then the analogy does not hold in your case, and buying boxes is a bad idea for you. You should still be able to follow the reasoning, however.
The topic of this thread is not semantics, btw. It's "how satisfied are you with those big box purchases". I explained that I am VERY happy with mine aesthetically, economically, and because I feel I am being frugal and saving money, morally as well, and gave the reasons for my feeling this way. Perhaps you might want to say something about your feelings about a box you have purchased.
