Brandi,
I hope all the information you need is available to you.Consider looking up that person seller's rating and feedback of other ebay users.If this is the seller's first time, then consider looking up in ticketmaster.com (if it's a big time concert or event) or another ticket agent to determine if the prices are somewhat similar to the tickets being sold. Maybe this person desperately wants to sell them at any price. Also, some people can get access to cheap tickets abroad, specially in Latin America.
There's a possibility it could be legit.. Hope this info helps..
