About the options
At the start each option is in white italic in the checkout trolley to the left.
Options are described one after another in this panel; as you select one its listing in the checkout turns blue or red if declined.
To change your mind at any time before confirming the order, click a blue or red option in the checkout and then select/decline it.
You will be taken through the options until you have selected or declined each one (you can always select an option you decline now after you have confirmed this order), and when you are ready to confirm, will be taken to the online payment page.
As and when your entry is (hopefully) nominated, you will then be offered another selection of options that are just for finalists. These are all explained in the Guide.
