I am a season ticket holder with the Rays and until this year I paid extra for the printed tickets. This year, the Rays switched to a small card similar to what so of you have mentioned.

I have lots of tickets from the Rays stored, but the only three I would say are in my "collection" are the Edwin Jackson no hitter ticket, the Matt Garza no hitter ticket, and the Game 162 ticket. All three are signed by the hero of the game. But now, if there's a no hitter or something, getting a "seat locator receipt" signed won't be the same. I'm kind of sad about the change, but I saw it coming for a while.
