Amazon has adjusted some of their prices on the soon-OOP Criterion titles, going up on eight of them and down $3 each on The Fallen Idol and Forbidden Games. They brought Pierrot le fou's Blu-ray price up to match the Criterion Store. I've updated the original post to reflect the new prices. Below are the titles that shamefully, opportunistically, went up in price $1-3 to even higher than Criterion sells them for:

Alphaville
Coup de torchon
Orphic Trilogy
Peeping Tom
Pierrot le fou Blu
Port of Shadows
Tales of Hoffman
The White Sheik
