Nah, its because they and their "novios" are just too cheap to buy them in the fancy malls...
On another note, i buy almost everything on Amazon before I buy it here. Besides fragrances. I bought several for me (Eau de toilette) and for my wife.
It takes a long time to arrive since this stuff is not sent by air. And when it arrived it all smelled stale. Maybe just bad luck. But next time I want to try to buy here.
