The ad made me buy the in-app purchase instantly, even before trying (it's placed nearly in the way of the action button).

So in my case, the ad worked as a immediate trigger to pay.

(I would have bought it a 1€ directly in the store, without any hesitation, too. So it made no difference in the end. I'm just a little annoyed that in the future I might have to restore my purchase).
