Amazon offers Prime members the Steven Spielberg Director's Collection 8-Disc Set on Blu-ray Disc for $23.49 with free shipping. That's the lowest price we could find by $24 and the best domestic price we've seen. (We saw it from the UK for $6 less in May of last year.) It includes Jaws, E.T., two Jurassic Park movies, Duel, The Sugarland Express, 1941, and Always.

Update: It's now temporarily out of stock, but can be ordered at this price for delivery when available.
