Criterion recently kicked off its semi-annual sale that slashes the cost of all of its in-stock Blu-rays, DVDs, and box sets. The sale will last through 12PM ET, October 23rd. This a great opportunity to save on deep cuts that aren’t typically discounted. However, it likely won’t be the last chance to get a deal on Criterion’s catalog of films; Barnes & Noble likely has another sale up its sleeves before the year’s end, and Black Friday is approaching.
