Got this email from Voidu saying to use this code for 17% off any PC game.
Hope you can find something.
Quoted from maskedmustelid below -
Once you have the coupon code entered in, it'll update all the prices you see whilst you're browsing the store, not just at checkout. Stacks with existing discounts, and seems to work on switch titles and pre-orders as well. Prices only in USD though.
