I bought my tickets for the Kessler fight on www.seetickets.com

Same as ticketmaster but Frank Warren TV seems to use this agent to sell the tickets IIRC.

The fight officially gets announced at a press conference next Tuesday - the fight is April 12th or 19th apparently. The second it's officially announced I'm booking my flights and hotel, got the best deals all lined up and bookmarked in my browser! I'm checking the web every half hour for updates becuase the second it gets announced all the cheap deals will be snapped up!
