How to add terms and conditions
All webstores need some sort of protection with regards to refund policies and terms. While we can't advise you on the content you can add your own terms and conditions from the General page of the Design section.
Once on the "General" page, you can select "Terms & Conditions" above the text editor. Then you will be able to enter your terms and conditions in the text field using any formatting you need and when you are done you can click "Update".
The content you create on this page with then be available via the link on the checkout page next to the checkbox required by the players to accept the terms and conditions before purchase.
