Amazon.com has a one day only sale. "Star Trek: Original Motion Picture Collection (Star Trek I, II, III, IV, V, VI + The Captain's Summit Bonus Disc) [Blu-ray]" for $34.99. I think the DVD collection was $22. I have these movies in DVD but have wanted to upgrade to blu-ray for some time I just didn't want to spend $85 to do it. At this price they are less than $6 per movie for blu-ray.
