The program's interface is very intuitive, and you only have to copy the link of the article you're interested in to start 'the hunt'. Once this is done, you must choose your highest bid and the program will place it automatically at the last minute.
Once you've programed your bid, you don't need to be online or keep your computer turned on for it to go through. This will allow you to win bids in a perfectly legal way without having to stay on top of them.
Myibay is a pretty useful tool for eBay fans, although it doesn't guarantee you'll always win.
