Fans of popular artists or sports teams know how hard it is to find good seats to live events at affordable prices.
Now, Ticketmaster will show you what seats are available in one place - both unsold ones and those up for resale - so you can price-shop a little more easily.
The nation's largest ticket-seller began rolling out its system, called Ticketmaster Plus, last month.
More than two dozen professional sports teams have signed up, including many in the NFL.
With the pro football beginning in earnest Sunday, millions of fans could start using the system very soon.
