Invalid clicks take roughly half a percent from us each month. I've never queried what those invalid clicks are because I wouldn't be sure I could believe the response. I'm sure G has a good reason for deducting a few dollars every month but they ain't going to explain to me why.
Now, if I was the BBC or Interflora they probably would explain with a real reason but that's another thorn in my, and probably your, side.
