One thing the article mentions is that there is a semicolon that can be seen, indicating it is a web-based order. That is not the case universally, it seems - my web-based orders do not have a semicolon after the app name on the order summary page.<p>You can tell, however, that it is a web-based order by the full customer contact info (including real email), as well as the additional developer-specific order number at the bottom of the page, when viewing the order details.
