This Sunday, Amazon has an interesting Blu-ray related deal of the day: up to midnight PST, you can order Ken Burns'
The National Parks: America's Best Idea for only $48.99 (62% off MSRP). The price history shows that this is the cheapest this six-disc documentary series has been at Amazon, although it has been cheaper at Best Buy during two of its own Deals of the Day, in June and October this year.
Thanks to forum member " Geologist."
This deal is expired now.
