BF Auction is a simple auction extension for Joomla! 1.5 that can be used to auction off surplus equipment to internal staff or for any other simple auction that you require. It's only a simple implementation, so it does not include any payment processing at all, and does not include any email notifications or automatic bidding. To bid on an item, the user must be logged in with a registered users account, there is no anonymous bidding.
