I did see it at, I believe, Neiman Marcus? Either that or Saks. I just checked their sites though and it's nowhere to be found. That's pretty unusual.
As for storing fragrances, I keep mine out of light. My room never gets terribly hot or terribly cold, so I don't worry too much. Back up bottles are a different story. I leave them in the basement because it will be awhile before I get to use them.
