You can link an order to a Showcase from 7 days before to 7 days after the Showcase (or up to two weeks after for Charity Showcases in 2 ways:
1. At checkout before entering the card details.
2.On the order page once the order has been placed. Select from the drop down box under the order status box the correct showcase and click link next to it.
You can link orders after they have been placed by going to "My Account", selecting "Orders" from the lefthand toolbar, and then clicking on the order number you're after. You'll then see a little box labelled "link order to an event".
Please note that we are not able to re-link an order to another Showcase once it has been linked.
