Right Big Country, people like dozens, but I thought maybe there was something special about needing a dozen arrows for some shooting event such as distance or target rounds that made sense. BTW, a Baker's dozen is 13 and sometimes 14. See the website above. Wouldn't it be nice to get an extra arrow or two thrown in when we buy a dozen?
