Sony Rewards offers 500 points
when you interact with the trailers for The Amazing Spider-Man
and share them on Facebook. (You must join Sony Rewards to claim the points; it's free to join.) That's the best such offer we've seen from Sony Rewards. (We saw up to 45 points for free earlier today, still available
.) The points are usable for buying Sony games, movies, music, and more through Sony's website.
If you've already earned points through the Spider-Man trailer, you can't do so again.
