This thead has a bit of rust on it. Current daily deals include:
http://www.cigarpage.com
Keep a close eye on these guys. While some deals are mediocre they have a few stunners now and then.
http://www.holts.com has daily deals several times a week.
Usually they recycle the same deals, so you need to be patient.

Usually these deals are over-priced, but every now and then they can surprise you.
For price comparisons I always look at
