A yearbook: This is the school yearbook. You can purchase the school yearbook. Typically all yearbooks are delivered at the end of the school year, directly to your school. All costs and deadlines to order are determined by your school. Learn how to order the yearbook here.
A Yearbook Ad: This is a dedication, advertisement, or baby ad that is part of the yearbook. Typically these are offered only to certain grades. Purchasing a yearbook ad is JUST the ad, it does not include a yearbook. You will need to purchase a yearbook separately. You will upload photos and text, but will not be able to design or preview your ad. All ads are designed uniformly. Learn more about how to purchase an ad here.
Yearbook Custom Pages: You can only order these WITH a yearbook. Custom pages will be individual pages that you can design on your own and they will be included in YOUR yearbook ONLY. Your school may have enabled or disabled this feature. If the feature is enabled, it will be available for you when you are purchasing you yearbook, it is optional. Learn more about custom pages here.
