Every day, Amazon offers up Lightning Deals, limited quantities of various products for a discounted price for a 4-hour window of time. You have to be on the lookout for these deals and once the item runs out, the sale is over. Meaning, if you see something on sale that you want, buy it immediately before it’s gone.

Typically you don’t know what will be on sale until the minute it gets posted, but as a prelude to Black Friday, Amazon has released the Lightning Deal schedule and prices for Movies & TV on DVD and Blu-ray for Tuesday, November 22, starting at 4:30am PST (yes, 4:30AM PST – that’s 7:30AM EST). See list of Tuesday’s deals here below, along with more information on how these special deals work.
