The standard price for a single copy of Centennia is $69.50. We also offer a special "group rate" of $39.50 per copy (plus shipping and handling) when five or more people order together. This pricing applies to groups of students, genealogy clubs, historical associations, and any special interest group. Know five 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). Note: orders will not be shipped until a minimum of five orders have been placed using your group code. Credit card charges will be refunded if your group does not reach the required minimum.

Try before you buy: if you have not done so yet, download the most recent version of the software and make sure it's right for you before you make your purchase. The free version covers the period of the Napoleonic Wars in Europe and is fully functional.

Order Centennia online with your credit card. Payments are processed securely by PayPal. Or if you prefer, order with a personal check or institutional purchase order by postal mail (our mailing address).
