The following has never failed me when ticketless. The less people with you the better.
Go to the game 2 hours before gates open and look around outside/parking areas etc just yell out what you are looking for. Get a feel for prices look for people looking to sell their extras to scalpers they most of the time rather sell it to you for a discounted price than the guy who will mark it up. If too high go to a bar for a half hour and then do it again.
Stand in the area of scalpers selling and say you are buying. Most of my buys have been people pissed off a scalper offered them just above face and rather sell it directly to a fan for that.
If that fails
The closer the game gets to starting the more the scalpers want to move them and if they made their money already on some occasions they will even go below face just because the amount people looking for tickets are dwindling.
