The math is simple but worth spelling out. A full bottle of Dior Sauvage EDP costs about $150 for 100ml. A 5ml decant costs $6. That means you can try 25 different colognes for the same price as one bottle of Sauvage. Here's why that matters.
The Blind Buy Tax
Every fragrance enthusiast has at least one bottle they regret buying. Maybe it smelled great on a paper strip but terrible on their skin. Maybe the first wearing was amazing but it became boring by day three. That $100+ bottle now sits in a drawer. Decants eliminate this tax entirely.
The Variety Advantage
Wearing the same cologne every day is like eating the same meal every day. Functional, but joyless. A collection of 10 decants gives you a different scent for every mood, occasion, and season — for under $50 total.
The Upgrade Path
Decants are the trial, not the destination. Wear a decant for 2 weeks. If you love it, upgrade to a full bottle with complete confidence. If you don't, you lost $5 instead of $100. Every full bottle purchase should start with a decant test.
Real Numbers
A 5ml decant at $5 = roughly 50 sprays = about 3-4 weeks of daily wear. A 10ml decant at $8 = roughly 100 sprays = about 7-8 weeks. That's enough data to make an informed full-bottle decision.
