I love Bidnapper. It frees you up so you don't have to wait by the keyboard for an item to get close to closing before you enter your first bid to not drive up the price. It's nice to use for an item you absolutely must have, and no one knows you're interested in it. I love it, and the only time I've been disappointed has been when my bud was too low. I buy in bulk and it's great they never expire until you use them.
