Has anyone seen the movie "once'?

We missed the final showing at the 19th st theater in Allentown, we thought it was to play at 7 but the last showing was at 4:30 so we missed it. Any ideas how to figure out where it might be playing? I googled it and there was one that asked for our zip code but it came back empty. Has anyone seen it for sale or rent online somewhere?

According to the web site it's still playing there at 4:30 😕
