What is criterion flash sale?

Unfortunately, as an AI language model, I do not have access to current information about Criterion flash sales. However, a Criterion flash sale typically includes discounts on a large selection of Criterion Collection films and DVDs. These flash sales usually occur a few times a year and are popular among movie enthusiasts who appreciate classic and contemporary films. Customers can save on individual titles or purchase bundle packages during a flash sale. It is important to check the official Criterion website or social media accounts for updates on upcoming flash sales.
