10$ celtics tickets

[General Mills]

Does anybody know if the celtics do the 10$ regularly? I went to all four of the games they did it and it was really great. By "it" I mean ticketmaster had a deal where it was 10$ a ticket. I think the ad for the deal was this on site but I can't remember . I was just curious if they do it year to year or something. Sorry if this has already been asked.
