So my guy called me back and here's the deal: The Ticketmaster surcharge has always been there. It just never showed on the seats when you click on them, only when you get to the third screen to make the purchase.
Here's the problem: The tickets directly from the Celtics don't show a surcharge. In other words, it looks like all the money is going directly to pay for the tickets and there is no surcharge to pay. That isn't true. The Celtics' tickets also include a surcharge, but it isn't broken out. I also have no idea if the surcharge that the Celtics' tickets get is different than that of the resale tickets but, because they don't list it out separately, I have a pretty good guess.
Bottom line: There's a reason that one set of tickets shows a surcharge and one doesn't, and the one that doesn't looks that much more appealing.
In the meantime, as a season ticket holder, I am now going to be looking at other ways to sell my tickets. There are clearly other ways to buy them. We have front row seats in Loge 9. I can do better than TM.
