Criterion takes 50% off all in-stock DVD and Blu-ray movies via coupon code "INGRID". That's tied with our February mention as the best sale we've seen from Criterion. Shipping starts at $5.95, while orders over $50 qualify for free shipping. Deal ends October 2 at noon ET.
A best bet is Slacker on Blu-ray Disc (pictured) for $31.96 before the above coupon, $19.97 after. With $5.95 for shipping, that's the lowest total price we could find by $2.
