Why per ml matters for dupes
A 10 ml perfume oil at $20 looks cheaper than a 100 ml Middle-Eastern EDP at $35, but costs almost six times more per ml. Clone houses selling 50 ml at $40–60 sit in between at roughly $0.80–1.20/ml, while the designer original usually lands at $3–6/ml. At five sprays a day a 100 ml bottle lasts around 200 days.
