Probably in response to the ongoing
Criterion sale at Barnes & Noble, Amazon has reduced the price of most of the titles released on Blu-ray so far by The Criterion Collection, which now can be purchased at 50% off MSRP, or $19.99 in most cases.
Nevertheless, B&N may still be the cheapest through the use of available coupons on top of the 50% off.
It is worth noting that, at the time of this writing, it is again possible to order '
The Third Man', although it is temporarily out of stock.
