Received an email from Rockstar Warehouse advertising 40% off all games and gear (this means things like tshirts mugs etc but not in-game currency oddly enough) until Monday (USA time … the end of Cyber Monday).
The free 500k in-game currency for GTA V is a PC-specific offer equivalent to wasting $12.99 on a "Bull Shark" cash card. Seems like a good deal for an official offer… no need to worry about VPNs.
The Funstock deal is cheaper.
