I ordered Wyeast from NB last week as part of a larger order, 3 day ground (it was only 2 bucks more than the $7.99 saver) and they shipped it with a little ice pack inside a cardboard mailer. I didn't even pay extra for the ice pack, I thought that was nice of them. Wyeast was manufactured Sept 8th, pretty darn fresh, smacked it, and it ballooned beautifully. Fermentation started very quickly.
