Laura Mercier Mineral foundation....

[JeremyVile]

Wanted to give this a go but cant see where to buy it. All I can find is the US site.
Loads of people have posted about it on here so where are you all getting it from??
Preferably I'd like to go to a counter so I can get the shade right but failing that if anyone has advice on the shades I'd be v grateful - I'm fairly pale and anything even a bit too dark looks awful on me.

Thanking you.

I have red hair, but am not porcelain pale. Have lots of freckles but they are not very obvious as my skin isn't glowing white. Not nicole kidman style. Probably more patsy palmer, but not as freckly.
(How disappointing, I look more like Bianca than a Chanel model....)
