You paid $599 for an iPhone; so did I. And then Apple reduced the price to $399. Now you are whining.
Please shut up about it, ok? I don’t want to hear it. If you didn’t think it was worth $599, why did you pay that much for it? Yes, it is cheaper now, so what? Now people who didn’t think it was worth $599 but is worth $399 will be buying it too. It is called supply and demand, that is how the world works, get used to it.
And now you get a $100 credit from Apple which is nice, but you don’t “deserve it,” you are not “entitled to it,” Apple is being generous.
So. Please stop whining.
