NOTE: This is an exceptional deal if you are also interested in purchasing the USB & SFTP add-ons and its awesomeness may depend on where you are physically located in the world. If you only want one, or neither add-on, (or in an unfortunate geographical location) you'll have to decide if this deal is right for you.
Haage & Partner, the official German distributor of Directory Opus, is currently running a sale through December 31st on Directory Opus. They normally sell the 1-user license for 69.95 Euros and include the SFTB & USB add-ons at no additional charge. Through December 31st, however, they are knocking ten Euros off that price for a total of 59.95 Euros VAT included. Live in a country that doesn't have to pay VAT (like me) and your check-out price gets knocked down to 50.38 Euros. At the current exchange rate, that worked out to be less for me than that BitsDuJour 40% off deal awhile back (because the add-ons weren't eligible for the discount).

GPSoft has already stated that there won't be another discount on DOpus of the magnitude that the BitsDuJour sale brought to the table for at least 18 months so if you were waiting for a sale to jump on the DOpus train, don't wait too long to jump. The train is leaving the station shortly.
