Is it possible to find cheap World Series tickets?

No, I would highly doubt that you would find a ton below $ 600. It is the World Series. All seamheads look forward to this all year, though they hate to see the season end. But, you most likely will not be able to find anything that is below that amount. The Major Leagues give the two teams a ton of tickets for their families and friends. Then, you have other people who reserve tickets already (big shots most likely). Then the lucky people that do have tickets, that are just fans, some will keep them, and the others may sell them on Ebay or Ticketmaster or StubHub. And they try to get as much as they can, obviously (by looking at prices for anything). So you’d be lucky to get too much below 600, and the closer the game comes…the more the price will rise. Good luck.
