Makes sense. I didn't know they used Birmingham though as well, I know that they use East Midlands Airport as a main cargo terminal. Its annoying because I work about 10 mins away from East Mids Airport, and the courier has to drive past me to get to the Stoke depot where I live...Not sure if this is true but took it from the EE forum.
I'm getting mine delivered to an EE shop so hopefully I'll know early one morning when it's going to be ready to collect and I'll pick it up on my drive home.
