Searched Hamilton Books and looks like there is a new selection of 3d movies available on the cheap compared to when I last looked. Examples include The Croods, Max Max Fury Road, King Kong Skull Island, and many others. Just watched King Arthur and Final Desination 5 and they are both fun fun movies in 3d.
Note a number of these have covers in Spanish but have available English audio track.
These would be great stocking stuffers for the 3d fans in your life!
