In the past, Literature and Latte (creators of Scrivener) have offered NaNoWriMo winners a coupon code for 50% off.
This year, they’re doing the same, but if you want to try Scrivener during NaNoWriMo, they’re offering a free trial (larger than their regular trial) so you can Novel away until December 7th.
I really like this software. To be fair, it’s the only special noveling software I’ve ever tried, but I like it. So if you want to give it a try, now’s a great chance to check it out!
