The normal price for a single copy is $89. We also offer a special "group rate" of $29.95 per copy when 10 or more people order together. This pricing applies to groups of students, genealogy clubs, historical associations, and any special interest group, even an impromptu group of 10 people. Know ten online friends interested in maps and history? Convince them to sign up and you all get the discounted price.

If you don't have a group code yet, and would like to sign up for one, contact us here.

Each member of your group should enter his or her ordering info below and include the group code (usually something like "AB2", for example). As soon as 10 or more members of your group have finalized their orders, we will charge you the special discounted price of $29.95 per copy and ship your CDs to your group members (N.B.: we do not charge your credit card(s) until we are ready to ship). And of course, you can also order all 10 (or more) copies at once if you prefer. If you are ordering multiple copies, please say so in the special instructions area of the order form. Order Centennia by filling out the form below. Online ordering is safe. If you prefer, you can order by phone, fax, or postal mail. We also have site license and single-user pricing options.
