World of Goo PC is the latest game on sale for the Direct2Drive (D2D) 30 Days of Deals (Deal$) sale. The Mac version is also on sale but it’s part of the Mac Monday deal. Price for both games is $4.99.
Use coupon code SHOWERS which is good for 20% off all games at checkout and the game drops to $3.99. That coupon expires today however. So if it no longer works you can find a 15% off coupon on the Promo & Coupon Codes page.
The same deal is going on at Direct2Drive UK. The game is priced £4.25 but after a 20% off promotion code the game is only £3.40. The UK 20% off promo code is KAPOW. It’s a code for Comic Con. The code expires today also but there are no 15% off codes available so act fast!
Same deals are going on at the IGN PC Store but there’s no coupon codes at all right now.
