Email from game basically saying the payment may be processed early and as i thought :
GTA V is released on 17th September and Rockstar, who publish it, have worked very hard to make it the
biggest gaming launch ever. They have requested that no UK retailer despatch GTA V before the 16th September
and GAME, along with all reputable retailers, will respect this request.
Your order is being despatched by Royal Mail First Class who have a 97.6% next day delivery rate. We will ensure
that your order is despatched via Royal Mail in time for release day.
So dont wait by the door monday folks, not that it should be expected
