Thats how I understand the problem:
Magento cant show a default shipping value in cart to guests or not-logged-in users because it doesnt know the country from a standard shipping address, right?
I only have one country to ship to (even only one global price) so it would be great if I could set that for everyone to see the shipping costs in cart even if guest or not-logged-in.
Is this right and can it be done? :)
EDIT: I mean the real costs in totals section -> NOT estimate
