So, I see this once in a while and most of the time I bite my tongue.
Generally speaking, perfumes are a luxury. No one ever died from a lack of perfume / cologne, and the like. And there is a subset of perfume consumers who think nothing of dropping major lucre on the rarest / vintage / newest / etc. They moan when the prices rise, but continue to buy - often much more than they will use in multiple lifetimes (hoarders much?)
Then someone drops the question of markup. High dudgeon ensues. To paraphrase: "OMG the latest Mona went up to $230 (that's for a 50ml bottle) and I think that's outrageous. How much markup is in these bottles anyway? We're all being fleeced"
I chuckle at this point, because I know, more or less, how the costs break down for them, and how many layers of markup there typically are. For giggles, I downloaded the Estee Lauder annual reports, among others, just to verify that Estee Lauder is not committing highway robbery. I recently found some old Neiman Marcus annual reports as well, and surprise surprise, NM is raking it in, but again not an unusual net profit for their niche. But these are all verifiable and it only takes a few moments' consideration to understand why they get what they get, and why you're not taking it in the rear when you buy this luxury item.
And if you Really Really Must Have The New Mona, then why are you bitching about dropping $230. It's either worth it to you, or it's not. Get over it, people.
