They're having a 2 day "VIP" preview Today (Wed Jan 22) and Tomorrow and don't officially open to the public until Friday. Supposedly you need the invitation that I received in the mail, but they weren't asking anyone for invitations.
I took a look around but they're not exactly giving anything away; at least not yet. Everything is about 20% off, which is what you'd expect at a normal sale. Nobody pays list price for furniture. There may be some better markdowns over the weekend.
