As a tip, before clicking on the final List Item With Displayed Fees button, glance just above it, it should read £0.00 Listing Fee.
If there is a fee amount listed there, you have selected an upgrade, and if you wish, it gives you time to scroll up and remove the payable upgrade.
This will show you a breakdown of any fees or postage taken:
