Street price: $700; MSRP: $700; deal price: $600

While this is an expensive speaker, a $100 discount makes the price slightly less painful. We haven't seen a single drop on this speaker until this sale, so it's good to see such a significant drop.

The Bowers & Wilkins Zeppelin Wireless Bluetooth Speaker is our luxury pick for the best home Bluetooth speaker. Seamus Bellamy and Brent Butterworth wrote, "Our blind listening panel awarded the Zeppelin a near-perfect score. In testing, it made well-worn favorites and fresh tracks that we've been digging of late absolutely crackle with life. That it also comes with the ability to function as an AirPlay speaker is icing on the cake. The speaker's shape and size might not work for some people, but after a few weeks of using the Zeppelin Wireless, we stopped noticing its presence except when it was filling our apartment with gorgeous sound. The Zeppelin Wireless is definitely a luxury item, but if you want to spend around $700 on a wireless speaker, it's worth it."

We haven't seen many good sales on this particular headset, with the best one being a brief sale last month for $128 through Newegg. This $130 deal is close, though it's only available on the black model.

The Sennheiser GAME ONE is the upgrade pick in our guide on the best gaming headset. Dennis Burger said, "Sennheiser's GAME ONE may cost more than most are looking to spend, but its spacious sound, stunning bass performance, and noise-cancelling mic make it worth the premium for serious gamers."

Street price: $700; MSRP: $1,000; deal price: $630

We've featured a couple of deals on new models of this projector for $650, and this sale drops $20 off of that price. We've seen some substantial drops on refurbished models as well, hitting a low of $517 once, but those tend to be rare.

The BenQ HT1075 Home Theater Projector is our previous pick for the best $1,000 projector. Our new pick is the HT2050, but we still think the HT1075 is an excellent purchase. Geoffrey Morrison said, "The BenQ HT1075 has one of the best contrast ratios in its class, more realistic color than the competition, and is brighter than some projectors that cost three times as much. For the price, it's truly the best in this range."

Street price: $90; MSRP: $90; deal price: $60

Here's a great deal on this Wi-Fi extender from D-Link. It has a shorter range than our main pick, but this sale makes it $40 cheaper. It's the best price we've ever seen on this product, beating the previous low by $5.

The D-Link DAP-1650 is the runner-up pick in our guide on the best Wi-Fi extender. David Murphy said, "Unlike our main pick, it can also be used as a wired access point, if you don't mind stringing Ethernet cable from your router to your extender. As an extender, its long-range performance isn't as good as our pick's, but it's great as an access point."
