The Gamer's Armory does not have it because they were told it was OOS. Maybe the stock was too low for them to place an order for the module?
I thought I read a post in one of these forums that someone had ordered BoBH through the CH website, but was informed it was on back order. Was there just a delay for building more games? I don't want to place a order for something on back order, I'd rather just wait.
