FandangoNOW has "hundreds" of digital movies available at $5 for purchase.
Note that a title must be UV on both FandangoNOW and VUDU in order for the movie to port. And even then it is not 100%. If in doubt ask.

Yes with Vudu’s $2 mobile disc to digital some of these may not be a great deal, but there are many titles that are not available in that service, so could be a good buy at this price.
Feel free to list titles that are worthwhile in comments.
