How do I prevent being asked to sign in during the last few seconds of bidding?

I lost several items to other bidders just because I was asked to sign in during the last few seconds of bidding wars.

How can I prevent this from happening?

Bid once. Bid your maximum. Don't get caught up in a bidding frenzy.

Then if someone bids more than you, he paid too much, the sucker.
