Here's one I've never seen people talk about. What exact time does the sale start? A while ago I learned that with Ticketmaster here in the US, you needed to pull up a government clock and click reload exactly between 2 and 3 seconds after the hour to get in. Too soon and you would be locked out, too later and others would have gotten 'in' before you. I've always wondered when exactly See opens it up as it could give you an advantage.
