ScoreBig, an online ticket brokerage, is offering 1,000 bonus United MileagePlus miles on your first purchase of $30 or more in addition to the normal 5 miles you receive for every $1 spent on a concert or sporting event. ScoreBig works differently than most other ticket brokerage sites in that you submit an offer (up to 60% off) for the tickets that you are interested in and then receive instant notification as to whether that offer was accepted it or not. Alternatively, you can redeem MP miles for event tickets as well. You will have to enter your MP number and pin for the offer, but you can feel confident that the site is legit as your name and mileage balance will be displayed. Full details here.
