I've gotten brisket in the mail. It is surprisingly good considering it was shipped accross the country. http://www.rudysbbq.com/store/c-10-smoked-meats.aspx
Better yet, show up in person on a Saturday before 11ish when they sell out of all their meat and enjoy some BBQ for breakfast! ;)
Last year I finally ordered one of their briskets shipped - it was nearly as good delivered. (Even as the last of its dry ice evaporated upon arrival.)
