I am in Toronto (Just it outside actually), and my way of buying tickets is to find a large corprate company like Flight Center who beats anyones price, then start shopping around via the phone to get a list of price's out there, then gettiing in touch with Flight Center and hagling with them for the lowest price. I have saved $100's of $$$ doing this.
Dunno if that helps at all, but thats my story and I am stick'n too it!
