GOG sale: Buy five games from this list, get them 80 percent off

Good Old Games is having a sale. They've got a list of twenty games for you to peruse, and you pick five of them, and then you buy them, and they're all 80 percent off. So you could, for example, get Pid, Puddle, Deponia, Divinity 2: Developer's Cut and Legend of Grimlock for a combined $15. That, my friends, is a small amount of money. You have about 6.5 days to take advantage of this deal.
