I think I'm wrong about the multiple releases. The K&L email blast said it was "new" but the lot # on my bottle matches D&M's website that says it was a 2012 release. So I'm not too happy that I paid $60 more for it. That's ridiculous!
edit - Every review online says Charbay S is aged under 2 years, but K&L says theirs is 29 months. That's why I assumed this was a new release. Lot numbers are the same on all bottles according to pics posted on the various retailers and review pages. I have some emails out to try to figure out what the story is. Either K&L is wrong or different batches went out with identical labels :/.
