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 within that four hours, 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 today’s Lightning Deal schedule for Movies & TV on DVD and Blu-ray. See list of today’s deals here below, along with more information on how these special deals work.

UPDATE: Amazon has lowered the price of ALL seasons of Mad Men on DVD and Blu-ray to $9.99 each from November 25-27!!! Visit the Mad Men page to select DVDs/Blu-rays to purchase.
