my guide is that when you are on the e-bay site bidding on an item. if you have to leave your computer for what ever reason ensure that you close down the site,(it only takes a few seconds to sign back in), or have a pass word protected screen saver. i have learnt the hard way with my children accessing the site while i have been away and they have bid on items without my knowledge. be warned,once it is done without your knowledge it's your money
.but if you are quick enough you can always access the site map and cancel your bid if you go to buyers tools.just enter the item number and your reason for with drawing.
