I used to try and buy a lot of perfumes some years ago. Unfortunately I concluded that it isn't really worth it since beyond some classics (Fahrenheit , terre d Hermes, declaration, narcisso for him, dior home, ysl m7, armani code, zv this is him, ck eternity, chanel egoiste platinum and of course aventus) there aren't many truly unique scents. Most perfumes try to copy another existing, mass appealing one.
Also male perfume nowadays is either too weak or too sweet (or too expensive if you go the niche route). So either I'll wear a perfume that will smell for 30 minutes and nobody will notice or I'll bite the bullet and wear a club perfume that will suffocate people (and not even smell good).
