Newegg wrote a big blog post about how they defended against a patent suit (some kind of common encryption method, though they reference a past case they won the right to use a "shopping cart" for customers to gather and add up items cost before purchase), and sent out an email with sale highlights at 3:40am (eastern). There's lots of stuff, like graphics cards and RAM that is almost finally back down to the costs I bought three years ago, but relevant to Head-Fi there's a pretty small selection of Bluetooth headsets, Klipsch IEMs (like the X5 for $60, supposed to be very comfy), and Sennheiser HD518 ($55).
The sale, Headphone department:
