Most of my bids are in the 5-10 cent range. I was going down my list and then I saw it: On one of my bids I set it to $10 rather than $0.10. It had been this way for at least a week. Luckily it was set on auto bid and the people below me didn't notice and kept their bids at $0.09 and below. If they would have been sneaky they could have raised their bids and cost me lots of money.
Moral: Check your bids a couple times after updating.
One of the things I sometimes do to see how much I am bidding is sort the column by my bid amount. That way, high dollar amounts show at the top (or bottom).
