I bought 2x Davidoff "Relax" 2.5 oz (75 ml) as it is aaaaaaalmost extinct here in Europe for about 60 euros each. Probably old bottles but they smell (both) like they are new and I am really happy with them. Will use them not that often so I can enjoy them for about 5 years at least.
Le Labo Santal 33 - blind bought 100ml. Loved it. $160
Blind bought Pure Malt - hated it. Gifted(SaintPaulia lol) it away. $70
Aventus & Azure Lime. Not a blind buy per se. More of a blind gift. A friend brought them back for me.
Iris Pallida - $115 - loved it
L'Air du desert marocain - $125 - loved it
Paestum Rose $120 - loved it
L'Anonyme ou OP-1475-A - $25 - loved it
Vetiver Extraordinaire - $240 loved it
Musc Ravageur - $240 - loved it
Santal Noble - $140 (vintage)
I would not take risks usually over a certain dollar amount, but my most expensive blind buy without officially sampling? I 'd have to say $80 for Chanel Pour Monsieur (non concentree, which I do love) 3.4 oz . I figured it would be a safe bet as I enjoy many of the other Chanels owned and sampled, plus others from the 60s and 70s.
around $120 after taxes and shipping on a 50ml bottle of Black Aoud. Found it to be an incredible scent, however, one that I really couldn't wear. Worked out very well for me, though, because I ended up trading it for a bottle of Pure Malt and I love that fragrance.
Creed Bois Du Portugal for full retail - in Australia! My daughter hated it and said I smelled like an old folks home I wasn't that fond of it either, although I can kind of appreciate it - just not wear it.
Been in the cupboard for a couple of years now.......... I'll try it again sometime.
