Actually, I bought a very good $45 infield grandstand seat at a (beautiful) Sunday afternoon Angels game in early June for $60 from a scalper who was working the Gate C game-day ticket line. It was close to game time and I just needed a single, so it didn't take much negotiation.
If you're going to buy tickets at the ballpark, carry a copy of the
Fenway Park seat/price chart so you can verify their location and retail cost. At the Gate C ticket window or talking to a scalper, be specific about your preferences -- "right field roof" or "infield grandstand" -- otherwise they'll tend to offer you the crummiest seats they have.
You can also get SRO tickets and plan to seat-jump after the first inning or two. There's no objection to anyone moving into empty seats, but wait until the crowd has settled in. On the other hand, if nothing opens up, you may end up standing in the back for the entire game...
craigslist swarms with scalpers these days, but you'll also see posts from good-hearted ticketholders (such as myself) who will make a point to offer their unused tickets to legitimate fans at or near face value. I've not heard of any problems with counterfeit ballgame tickets, but wouldn't touch a computerized "print your own" ticket, which is WAY too easy to copy. As to the "Scalper Free Zone outside Gate B" referred to in the Mercury News article, forget it -- there's no such thing at Fenway.
And most important of all, Good Luck!
