You know some people actually have a thing called a job, therefore can't be at home waiting all day for a courier to turn up which could be from 9 - 5.
Therefore collecting on lunch break, or whatever, plus there are other stores that sell it instead of lining for hours at an Apple store, I got the iPad 2 in ten mins last year at a different store.
Just an idea...you could have it delivered to work, or delivered to someone you know will be home during the delivery day (if you trust they won't unbox it while you're at work!)
