More limited edition collector fragrance bottles, with the usual disclaimers: in most of these cases, the juice is unchanged, just the bottle is “special” (or not, as the case may be), and some of these may not be available in the US.
From Estee Lauder, the Sensuous Collector's Edition with bulb atomizer. Coming in April in 50 ml Eau de Parfum, $65. (via cosmeticworld)
From Jean Paul Gaultier, a limited edition of Ma Dame with "kiss me love me" on the front. Why, I don't know, but it's 60€ at Sephora in France.
Strictly speaking, this doesn't qualify as a collector item, but it's too cute to ignore. A limited edition solid fragrance for the limited edition Wild Cherry Tree / Cerisier des Oiseaux from L'Occitane. 12€ at L'Occitane in France.
From Hugo Boss, the "One Fragrance One Tree" project, in collaboration with Pur Projet: buy a specially marked bottle of Hugo Man or Hugo Element, and they'll plant a tree in the Peruvian rainforest. A "personal tree code" on the package will allow the purchaser to see the location of the tree via Google Earth. Both bottles can now be found at Douglas in Germany.
