I buy samples of expensive stuff (like Creed scents) before throwing money into a full-size. It's saved me hundreds as there are some that just don't smell good on me. I'm currently debating the Aventus purchase as it's one of the better ones. However, even though I really liked Bois Du Protugal, but found the Guerlain's Heritage gave me the same vibe and cost about $200 less.
Welcome to the club - Guerlain's Heritage is a phenomenal scent. If you are looking for a real classy and sophisticated fragrance you cannot go wrong with Heritage.
