If the iPhone is considered "expensive" due "high import taxes" at $920, how is it selling on the black market for $3500?
The game for selling $920 iPhones is "find a price point were demand times price minus cost is maximized".
The game in the black market is "find the highest price point at which the inventory sells out quickly enough".
If the price of a black market iPhone is higher than that of the legal-market iPhone, with any regularity, it suggests that $920 isn't a problem, let alone the import tax portion of that: supply must be the problem.
And if the price only hit $3500 in a couple rare situations (errors, morons), I'm not sure why they even brought it up as if it were common, as that fact completely undercuts the argument about the iPhone being too expensive.
On the black market, iPhone 5s have even been reported reaching over $3.500
Unless there's something special about them, maybe jail-broken with a few grand worth of apps on it? (Not really buying that, just noodling).
They're not carrier-locked, when purchased direct from Apple for $920, are they?
And if they're selling for $3500 on the black market, exactly how "expensive" can they be, at $920, let alone how could they be "expensive" due the import taxes that result in an official product that's less than one-third the price of the illegal product that skirts those taxes?
