I just received a firm confirmation from Guerlain USA PR team that their Spiritueuse Double Vanille is not being phased out or discontinued. Not that the rumors made any sense. Spiritueuse Double Vanille is such a popular perfume that sells very well (and a newish Guerlain formula, unlikely to clash with IFRA), but we're all prone to discontinuation panic. So, no hoarding necessary for now.
