Pls, I'm confused. Where is the best way to buy the museum pass? I want to order it online. Will I be charged shipping and handling fee, or are all vouchers type and I have to go someplace to exchange it for a pass?

Here's the URL I used to get my museum, metro and chateau passes: http://www.parisplus.com/Pass_Product/parispass.htm.

I had them in a couple of days.

Good luck.

The best way to buy the museum pass is to purchase it at the first museum you go to in Paris. I usually purchase it at one of the smaller museums like the Rodin or Concierge.

I'd buy it in person at a less busy attraction. You will only need to pay the face value of it, without any shipping & handling fee; and possible service charges. When I was in Paris, I bought mine at the Concierge - no line ups.

Don't worry about it - get it when you're in Paris, and plan your museums and monuments visits. When I got mine, I planned on Concierge, Ste-Chapelle, and the Louvre on that day.

You can see the list of attractions the pass covers:

Do NOT order over the internet--it is unnecessary and more expensive.
It may even be iffy if you want to get one, depending on when you are going and how much museum going you will do. They are now 2,4, and 6 days. Buy it at a smaller museum--they have, unfortunately stopped selling them in the Metro.

suzy,
It's much more expensive to purchase them online and so easy to buy when you get there. We bought ours at the Pantheon one trip and at the Musee Delacroix another, and neither were busy at all. Even the Louvre wasn't busy the time we bought them there, as it was in the evening.
