Price Extensions - Internal Error
I assume you mean the prices that are listed under the title in organic listings?
This is specific price markup/microdata in the HTML itself and it's not updated in real time.
I'd recommend asking over on the webmaster central forum as they'll be able to offer a bit more specific advice on this: https://productforums.google.com/forum/#!forum/webmasters
Sorry I can't be of any more help right now.
