On the Pacific Center location:
The prices are the same as the Canadian prices on the Sephora site.
Pretty much still a gong show from opening till close...lots of stuff out of stock, picked at, etc.
If you have to go, I would go in the early morning.
If you are going to be buying more than $120 worth, might as well buy it online with the free shipping and samples.
I got an awesome Sephora umbrella for free on opening day. Woot!
