Try dabs.com, it's one of the cheapest in town. You will pay about 30% more on a lot of items than you would in the US.

You could order form the US and have it shipped to Paris but by the time you have paid the duty you will pay the same amount anyway, also there is still a few items that the US wont export.

I remember a couple of years ago it was actually illegal to ship anything over 400mhz out of the US as it was classed as weapons grade technology, whether they actually enforced that or still do i have no idea.

Welcome to the rest of the world.
