Crystal Rich has a 30% off New Year's sale on new Zentimo Pro purchases until 1/1/2013.
They also have a lifetime license again (they did not when I last upgraded), which costs about twice as much as a one year license, although those who remember how the developer handled USB Safely Remove lifetime licenses may not be swayed by that.
If you need to upgrade an existing license, the upgrade price is still a little better than 30% off.
