In time for Halloween as well as the beginning of the gift-getting season, Criterion is selling every Blu-ray and DVD in its hallowed collection at 50% off their usual prices for one day only. These sales only happen a few times each year (and when they occur is pretty random), so if you or a loved one (or even a marginally liked one) enjoys adding flick after flick with Criterion’s gorgeous box art to their shelves, we recommend taking advantage of this 24-hour sale that ends 12 p.m. EDT on Oct. 23.

Still a couple of hours to go.
