Wow, so far so good in my opinion.
For Montales I hear a lot of people get samples from a MUAer/BNer called Maisonstinky. I've still yet to order samples from him so I'm not sure what they are like yet.
The Bond No 9 samples are so cute! Might be a little juvenile to some, depends on her personality I guess.
I'm finding with the Etat Libre d'Orange line that the names are often far more provocative than the scent. Then again, I have not tried Secretions Magnifiques. Some really nice fragrances in there though.
With the Ayala Moriel scents there is a personality quiz which Ayala reads and sends you recommendations of her line from your responses. That might help with choosing. She is also very nice and helpful.
Haven't had anything to do with LV, PG or TDC yet and don't know about their sampling programs or their scents.
Good luck! I envy this girl
