i had this email in the OP yesterday morning but i was not allowed to start a thread here about it
i have not had problems with Game & the games are not sent out the day before but a few days before & are left waiting in the post office depot & will be sent out so they arrive on the right day, i did find this out from Game in a email years ago i think the parcels have 24hr stickers on them as they are a different delivery, i have had this a few times, mostly on when i have the limited or collectors edition so it is in a bigger box, i think the normal version are classed in the same way though.
i luckily had the week booked off ages ago before the release date was announced which is a bit of a bonus.
i have the collectors edition on order & will also get access to the blimp
GTA5 is the seventh generations last hurrah !
