Got a work related variant, a 3 letter domain we really liked was registered by a person asking a couple of hundred bucks or so. Which really was a good deal and we were more then happy to pay.
Our IT department advised guiding the transfer themselves. Instead our marketing department went ahead anyway and just agreed to "you end your subscription and after that we register it" ... instead of using transfer codes.
In the minutes between, a bulk claimer snatched it away.
