You can get fairly good prices at http://www.ticketmaster.com/ . The biggest trick is remembering to buy early, and look for time specific deals.
You can find some cheap tickets in your local ticket shop, or you go to the concert and wait for someone to sell you a cheap ticket. that is the best way.
There are many sites that re-sell concert and other event tickets to potential buyers on the web. The most well known are Stub Hub, Cheap Tickets, and Go Tickets.
Concert tickets are expensive if you buy them directly from Ticketmaster.com. If the show is not sold out, you can probably find a good price at Ebay.com or Craigslist.com.
