We don't come across a ton of great projector deals, but this Acer 3D Home Projector for just $405 is definitely one of them. Lumen level and lamp life are both great on this Acer, and it also happens to be the Wirecutter's pick for best sub-$500 projector. [Amazon]
It's not the most customizable router in the world, but Apple's new AirPort Extreme supports 802.11ac, is dead simple to set up and maintain, and looks good enough to put out on display. Today you can pick one up for $165, which is $35 off MSRP, and $20 off Amazon's price. If you want a high speed 2TB drive built in for backups, you can also pick up an otherwise identical Time Capsule for $250, which is $50 off retail, and $28 off Amazon's price.
