How are Guest checkouts handled?

Country field is required in checkout page even if its an existing customer or a guest. So you can go for it. You won’t get a blank country name.

Thanks for your reply. In that case, I don’t quite understand the results I’m seeing. I’ve attached a screen print here:

The top row is ￡18967, but there is no country code there. It can’t be the total because it doesn’t add up. (The last country in the list is Singapore, so you can see all the results in that screen print).
Can you help me to explain this please?

I think its not an issue of blank country name. Let me check. I’ll try to fix it in next release.
