And I repeat: there was no guarantee that everyone who wanted to take advantage of the promotion would be able to do so.
Even after having done all that, it's completely possible that you wouldn't have gotten a phone.
They're repeating this promotion not once, but twice. If your priorities are such that you will modify your schedule around the ability to buy a phone at a discount, then you should be glad they're giving you two more opportunities to do so. That's better notice than you had for the original deal, which they didn't even have to offer at all in the first place.
