Update: Expansys informs us that they've encountered high demand for the reduced-price Nexus 6 and have exhausted their stock. Sorry, folks, they're back to regular price now!
If you still have yet to get your hands on a Nexus 6, you can currently snag one at a discount from Expansys — so long as you're only interested in the Cloud White option. The reseller is currently offering that particular flavor of the device for $605 unlocked.
Newer model: Nexus 6P
The Nexus 6 hasn't been particularly easy to pick up since its launch, so this may be your best bet on securing the 6-inch monster. To top it all off, you'll save a $45 off of the devices normal price. Keep in mind, however, that this is only for the 32GB Cloud White version of the device, and the deal is only for today, so act fast if you're interested.
