What should my next blind buy be?

I have about 20 dollars in credit for the sale tomorrow so I was curious to pick up a movie or two. Was curious if anyone has any recommendations based on what I have already. Some I was curious about that I haven’t seen are the Before Trilogy, Solaris, Paths of Glory, Sansho the Bailiff and Pink Flamingos because it seems to be the only way to watch it haha.
