Bid Monkey is a command line tool, written in Perl, created to automatically place a bid on an eBay auction at the last minute. It will run in the foreground or background, and only requires basic information from the user, such as username, password, item number, and the maximum bid to place. Its most unique feature is that it will automatically determine the auction ending time. All you have to do is tell it how long before the end of the auction you would like to place your bid. Bid Monkey will work internationally (eBay.de for example) due to the fact that any item number can be viewed through any eBay site.
