there not doing it by alphabet or anything like that, if u think about it, they hav multiple outlet sources to distribute the fones, so they probably distributed the order list amoung lets say 6 outlets for example, so each store has a list of orders. But the problem with this form of distribution is that any one of these stores may have 50 orders ranging from the september to december to get thought, but as these stores have limited stock, say 40 units, it stands to reason that people whose orders went thought to these stores would have order dates from september to november.

But because not each store recieved the same levels of stock, or aren't processing them as fast, it creates a situation where people who ordered late recieve the fone early purely because of the distribution method. In short, multiple stores, multiple order lists, multiple stock levels = unfair distribution...

just my thoughts tho lol as with everything MPD related, it can never been 100% accurate!
