If it sounds too good to be true.....
Remember how many people out there only catch the, "Never expires," but completely miss the, "Non-transferrable." It might be a fast way to make cash, they think, when in fact, they really don't understand what they're selling. For those who are selling lots of them (I've never searched for this before!), are they coming by the tickets legitimately or are they frauds? You could be the responsible party if you're caught at the gate will illegitimate passes.
