They may do this every year (I don't know) but Scrivener is running a special promotion for NaNoWriMo. If you download the trial version of Scrivener here...

...instead of a 30 day trial you'll get to use the trial version from now until December 7th (so you have time to prepare for NaNoWriMo and write during November without worrying about Scrivener's trial running out). If you download the special edition (link above) you automatically qualify for 20% off if you buy before December 7th. If you write 50,000 words in November you'll get 50% off. You can download this trial even if you've tried Scrivener in the past.
I actually got this working in Wine on a Linux computer – but not the computer I usually use. But it's okay since I can run the computer remotely (within my home network) with NoMachine (nomachine.com) on any computer (free). I found I can even log into this computer remotely by Zerotier (zerotier.com) to my network (also free). This way you don't have to worry about syncing.
Now if I can only get up the gumption to write 50,000 words in November – about 1,600 words a day – I'm all set.
