UPDATE! That's all, folks! They literally sold out what limited supply they had in minutes. The only deal now is $50 off either the 16 GB or 32 GB model. Again, while supplies last. Damn that has to be the fastest sale I've ever seen short of a Nexus launch in the Play Store.
This is a "until supplies run out" sale, so get a move on it! For $199 it is a hell of a deal!
Oh, it's U.S. only too. Sorry everyone else, blame HTC. Not the messenger.
Direct link to the sale can be found here.
For the record the normal price is $399 for the 16 GB model. So this is half off and that ain't too shabby.
