Servers are bumpy, but HTC's starting up a "Hot Deal" promotion that drops the 16GB Nexus 9 to $199. Once the limited quantity is gone, both storage options (16GB and 32GB) will save $50 through midnight EDT tonight.
Aaaaaaand it's gone. All sold out. But we might see more "Hot Deal" promotions from HTC in the future, so we'll let you know if and when that happens.
