More information: YSL's vintage Opium line by L'Oréal

For the past few years, the vintage Opium line, reads: Opium (2009) Eau de Toilette / Opium (2009) Eau de Parfum versions, by Yves Saint Laurent has been gradually disappearing from the perfume market, only being sold in France and a few other parts of Europe. I wonder what's happening to the line, which I used to find "quite easily" on certain U.S. perfume websites. Does anyone know if the line is being discontinued, especially the Opium (2009) Eau de Parfum, a version I like more. I emailed L'Oréal Luxe, but they don't respond, and if they do, they're incoherent and don't provide any definitive information! What a stress. If anyone knows more, information and details on what's in happening, that would be greatly appreciated. Xx
