Steam might have eliminated flash sales and dailies from the equation, but GOG is remaining ever ruthless with our free time with the return of the latest Insomnia sale. The Sleepy Sheep Insomnia Sale is running from right now until stock has depleted on all the games on sale.

The catch is that there’s no regular rotation. It’s one game at a bargain price until every copy has gone, and then the next game is up. Obviously what this means is that there’s no checking back in at a specific time, so you’ll need your wits about you to grab the best deal.

GOG is kicking things off The Witcher 3: Wild Hunt at a pretty decent £17.49, but copies are going at an alarming rate. Apparently that’s the lowest ever legit price, so I’d advise you snap that up if you haven’t got it yet. Oops. All gone. Look, you’ll have to be quicker than that.

As a little bonus for those who feel like truly punishing their wallets, is also throwing in a random free game for every 10 games you buy. Which sounds a lot like throwing good money after bad if you ask me, but I know these things are difficult to resist.

Keep your eyes peeled and let fellow GD’ers known in the comments below if you spot any stone cold classics crop up in the flash deals!
