thanks to all who have posted their experiences, very helpful. so far have gotten replies from Hermes and Annick Goutal saying they will send samples. Seems to work better when I include my address in inital email -- good on ya to whoever posted that little gem several pages upthread.
1/23/12 - SCOOOOOOOORE! Came home to a nice package from Hermes w. 2ml samples of Kelly Caleche, 24 Fabourg, and Elixir De Merveilles. Can I just say OMG KELLY CALECHE IS MY NEW DRUG OF CHOICE.
1/30/12 - JACKPOT, YOU GUYS! Piguet sent two samples of Fracas (I can make that last FOREVER) and the SAINTS at Goutal sent 6, count em SIX, samples. Un Matin d'Orage, Gardenia Passion, Petite Cherie, Ninfeo mio, Rose Absolue, and Eau d'Hadrien. Who says there's no free lunch??

FYI the email I sent to each house was very basic -- just saying I'd like to smell before I buy, don't have niche stockists near me, would like some samples. The only time I actually specified was with Fracas. Luuuuuv me some Fracas.
2/2/12 - Did a happy dance when I opened my mailbox and found 1.5 ml samples of Agent Provocateur and L'Agent from AP, along with little packets of AP body cream and "body sauce." Not sure how I feel about "saucing" my body, but whatevs. Annnnnnd from Divine, Divine and L'infante both in 2ml sample sizes. WOOT!
