On the Louvre website it is possible to buy advace tickets for a very small charge. However, it seems that the only option is to have them physically mailed. Does anyone know of a way to buy ickets over the internet and have them emailed?

You can pick up the tickets at FNAC.

It's a ticket service, you can pick them up at the store. YOu cannot have them emailed.

I got ours for our visit next week and they arrived by mail within a few days.

Dukey - which service did you use?

You can also purchase a Paris Museum Pass that allows passage or decent discounts to most museums and Versailles. With the pass they allow you to bypass the lines and pass through to the museum. You can purchase the passes through RailEurope before traveling to Paris or just pick one up at most Metro Stations. I've seen the line at the Louve be over a 3 hour wait and we passed right on through like we were royalty.
