Amazon has an interesting BD-related deal of the day going on now. Today only, you can buy
Planet of the Apes: 40 Year Evolution Blu-ray Collection for only $42.99 (67% off MSRP). This offer expires today at midnight PDT, or when stock runs out. This five-movie box set had been briefly available for $49.99 in December 2009, and then $45.99 in February.
