I looked at the code of wp-content/plugins/wp-ecommerce/options.php and searched for “admin”. Since it looks like, as people above has menionted, the links are broken at the top of the Settings page, I found the “correct links” in the file.
Here are some that work. They are they basic html version; the pages aren’t stylized at all. Here they are.
yourwebsite.com/wp-admin/admin.php?shipping_options=true
yourwebsite.com/wp-admin/admin.php?payments_options=true
yourwebsite.com/wp-admin/admin.php?checkout_options=true
Updateing info in these pages does show up on the checkout page, etc.
