Because I'd be a newbie who had never smelled Sélection Verte or Cyprès-Musc, Bois du Portugal or Epicea instead of GIT (and good luck finding SV on eBay--or from a seller here.)
For that matter, though none of the following smell like MI, I doubt I'd ever have smelled other Creeds like Royal English Leather, Acier Aluminium, "Vintage" Tabarome--or even the readily available Himalaya or Erolfa.
(Or even Aventus??)
this is meant as encouragement to explore the not so well advertised scents for men from the house of Creed, not condemnation in buying two of their pop frags which have been advertised like crazy and discussed on threads like these many times before.
May I humbly suggest you look up the reviews on the "rare ones" I've mentioned and, if you don't live in a large metropolitan area, order a tester from somewhere, should any of the reviews sound intriguing
-- And of course, decide for yourself.
