$50.24 usd on Steam atm, and GTA IV is $7.49, GTA III $3.74, Vice City $2.49 and GTA IV Complete Edition $13.99 (Steam Sale only lasts next 5hrs) CBF making a listing for these, to many neg ravers and too much effort for only 5hrs left, but if your here, then you are looking for GTA stuff and you found it.
It's cheaper at Funstock. Use OCT-COUPMAIL-HOT20 to get the price to around $46 AUD.
