This is only true if you have converted to a paid app instance. As far as I can tell from the following - http://code.google.com/appengine/docs/billing.html
Developers can consume a certain amount of resources for free and it is only upon conversion to a paid instance that you start to pay the prices listed in the enclosed url. i.e. the $0.08 for Frontend, etc; Hope this helps regards paul -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
