I had an ad campaign in progress which I cancelled on Tuesday. With the data delay, it kept running, and running, and running. It was like an ad campaign on steroids...30,228 impressions and 203 clicks. I would have put in a formal complaint, but I sold quite a few books during the campaign. After a certain point, the click column kept increasing, but the Spend column did not. Perhaps they knew it was terminated so they let it slide? Or, am I going to get pelted with a HUGE charge once it all catches up. My bid was very low so I'm hoping it won't be too awful.
