I agree with this. Stubhub is excellent and very legit. As stated, it's good if you want to pick up last minute tix to an event that isn't in great demand. I went to a NY Jets / Carolina Panthers preseason game a couple months ago in MetLife Stadium. Bought the tickets a week earlier from Stubhub and was sitting in like section 135, row 17, and paid half of face value. The tickets included a parking pass (usually $25) and I was able to print them out instantly.
For an event like Mania, or even top notch seats at Raw you'll be paying a lot above face value. As the event gets closer, some seat prices on those sites will drop as scalpers, "ticket flippers" (buy them low, resell them high with no intent on ever attending event), or people that simply can't make it to the show will accept less $$$ for the seats.
