This has been a problem before on this site. The listings are put up by the company's resellers. Event Tickets Center is not the dealer (they don't actually have the tickets themselves), but instead are just a broker, matching buyers and sellers. The identity of the sellers is hidden, but those sellers are able to create listings. There have been a few documented instances of events being listed before the tickets are available or even of events being listed that didn't actually exist. Event Tickets Center will ensure you get genuine (not counterfeit) tickets, but they will not guarantee your satisfaction with the purchase. It is entirely possible you could purchase tickets that are three times face value from this site, even when those same tickets are readily available from the primary source, like Ticket Master. Be careful.

Hi Tracy, EventTicketsCenter.com is a resale marketplace. Tickets on our site are posted by thousands of companies and fans who list their own inventory. They acquire their tickets from primary ticket companies, fan clubs, venues, teams artists, management and others. All ticket purchases are guaranteed to ensure you get the tickets you ordered.
