I always use stub hub because usually if you dont buy concert tickets the min they go on sale chances are you wont have any luck because they will sell out in 2 hours. Many companys use bots aka automatic computers buy out close to all tickets to popular concerts so they are able to resell them while making a profit. Stubhub is much like this yet your dealing with an actual person. Lets say a person was lucky enough to get a ticket from ticketmaster from this concert worth $100 ....they could go on stubhub and charge $150 for the ticket and make a $35 profit.....they would only make a $35 profit and not the whole extra $50 because stubhub takes commission from ticket sellers and taxes (and that's how stubhub makes their profit) :) its all legal and as far as I know very safe. Ive never sold tickets but ive bought many tickets from that site including this concert :) Had to pay close to twice the face value (because coldplay and jayz make it a high demand concert plus the fact its a new years eve concert makes it a higher demand) but on a reg. Day ppl who sell tickets on that site usually only charge 25% more but for this concert prepare to pay twice the face value :) VERY WORTH it ...since it Coldplay ...new years n sold out hehe
