I picked up a copy of Gears of War 4 today but the codes for Gears of War 1, 2, 3 and Judgement are all surplus to requirement as I already own them on Xbox 360.
I'm therefore selling the codes. The going rate seems to be £7 for all 4 codes.
The codes will be sent via e-mail once funds are received via PayPal.
All the best
Price dropped to £5. Can send a photo of the codes on receipt of payment via PayPal.
