GameStop.co.uk reveals its own Grand Theft Auto V trade-in offer

In what is likely to become a recurring theme, GameStop has revealed a Grand Theft Auto V specific trade-in offer.
The UK website has released a list of 200 games, any two of which can be handed over allowing GTA V to be had for just £4.97.
However, this offer differs from Amazon’s GTA V deal in that it still requires consumers to pay the full £39.97 up front. When the game arrives in the post on release day it will come with an envelope that can be used to post off the two trade-in titles. A user’s bank account will then receive a £35 refund within 10 days.
Games listed in the promotion include GTA IV, Just Dance 4, LEGO Indiana Jones 2, NHL 13, Star Wars Kinect, Mario Party DS, Injustice Gods Among Us, Little Big Planet Karting, WRC 3, Zelda: Skyward Sword and Defiance.
The full list, including the required formats, can be found here.
UPDATE: MCV has been informed that GameStop's deal went live before Amazon's.
