I’m always hesitant with Best Buy for preorders of highly demanded devices. It just seems they probably request a certain number but don’t know exactly how many they are actually going to get on launch day until they get them. And then you have to wait for them to call you to schedule a time to pick up the device. And sometimes that call never comes, on launch day.
My experience has been the pick up orders have to go to the mobile section. So it’s not like you can just go to customer service and pick up there. No, you had to actually sit with someone. Maybe they have tweaked this process but I will probably always have these reservations with them.
