Tips for Buying Event Tickets Online

Your wedding anniversary is coming up and your wife is dying to see Clay Aiken in Spamalot. Unfortunately, tickets are sold out on that special night.

The Yanks and the Mets are tied in the Subway Series, and you must go to the final game. The only seats left are nosebleed.

Madonna's going on tour?! Ticketmaster.com is flooded with fans, and all three shows sell out in less than five minutes.

Many consumers facing these dilemmas have flocked to Web sites like StubHub , TicketsNow, RazorGator, TicketLiquidator and TicketExchange, where fans and professional brokers resell excess tickets. Forrester Research projects that the $2.6 billion online business will nearly double by 2012.

However, the opportunity can come with a hefty cost -- sometimes hundreds or thousands of dollars more than the original face value of the tickets.

"It can be a tricky game," says Tod Marks, senior editor at Consumer Reports. "If you don't know what to expect it can leave you feeling ripped off."

Consumer Reports, which is published by the nonprofit Consumers Union, tested the sites to figure out how to score the best prices. The strategy involves a game of waiting for the right moment while gauging demand.

Just a week before a Yankees-Indians game, Consumer Reports found first-row seats behind home plate for $22 less than face value. But, at the time, the Yankees were in a slump.

On the other hand, a Santana concert ticket would have cost $232 -- more than twice the initial face value -- three weeks before the May 20 show at the Filmore in San Francisco. Those who waited in line at the box office a half-hour before the event got a much sweeter deal: $92 per ticket, just $2.50 more than the original value.
