Growlers absolutely ship fine. Its usually best if you can get the 32 ounce flip top. If they are screw top the black plastic ones are better as oxygen barriers, but just tape the lid really well, I have drank many a shipped growler and they are always tasty.
If you don't have this filled up by Sunday I'll probably join, I can fulfill the requirements without buying a single beer, and it would just be cost to ship, which is low with a light box, so I'll keep my eyes on this thread...
You know you want to...
