The store opens up at 8am (Can pick up as soon as they open)
Can install at 1PM
Can play at 5pm.
All correct information. But 8am is one hour before the 9am Blizz stated. This is important for the CE people as you don't want to miss out or anything getting your CE. So there's still time to contact your local EB Games to see if your local is opening at 8am or 9am.
