TOPIC: Google Checkout Signed Carts

If you must turn on "My company will only post digitally signed carts" to use Google Checkout, do you lose the ability to use Google's own "Donate Now" and "Buy Now" buttons? (The buttons that you can generate within your own Google Checkout account.)
Thanks.

Daniel - actually not sure about that one. That would be a question for the Google Checkout people

Reading the Google Checkout documentation, it looks like one would not be able to use these buttons if only digitally signed carts are allowed.

Is turning on "My company will only post digitally signed carts" an absolute prerequisite for using Google Checkout with DT Register?

With the type of integration that is used, I believe it is required. Unless someone wants to chime in that has successfully used it without... I'd go with that. We integrated Google Checkout a while ago, so I haven't tried it without that setting for a long time to even remember what exactly happens.

Anyone out there using Google Checkout without this setting?
