Yeah, that place is fantatic for price reductions. That same shipment also contained Lars Von Trier' ZENTROPA (widescreen subbed!, despite FS on the packaging), Michael Powell's GONE TO EARTH, MONDO CANE (only crappy print in the batch), Alain Resnais' NIGHT AND FOG, TERMINAL STATION, Powell & Pressburgers THE LIFE AND DEATH OF COLONEL BLIMP (beautiful Criterion port), 20,000 LEAGUES UNDER THE SEA and a couple of others I can't remember, all for about $4.71 US each!!!
They call came from their Classic DVD Collection sale, which is still ongoing, with titles replenished from time to time:

They just launched a Premiere January Sale that has even more of this stuff.

Virtually every European or American movie I've purchased from them would appear to be direct ports of the R1 discs, often with many of the extras, so for the price, you can't go wrong.
