It's RueLaLa, judging from the upcoming boutiques.
I haven't ordered anything from them yet, but I knew about them before Gilt. They do have some amazing deals. Mostly fashion & accessories but the occasional stuff for the house. Wustof and Waterford have been featured a few times.
I've been on RueLaLa for a few months now. They are affiliated with smartbargains.com so if you've ever shopped there you've probably gotten an invitation or two ;) IMO, their prices are nowhere near Gilt caliber. They had a Prada sale a week or two ago and prices were 30% off or so.
