I'm not sure how long this sale will last, but I just walked into my local Best Buy and walked out with Blu-ray's of Jack Ketchum's The Girl Next Door and The Lost for a mere $6.99 a piece! Also on sale and worth noting was Grace, which I already own. The Blu-ray's are located by the registers and you should see them as you head over to pay. The sale is also available online, with titles like Stan Helsing, The Alphabet Killer, While She Was Out, and Red Mist all at this incredible blowout price. Most of these movies are crap, but I highly recommend you take advantage of this sale and pick up Grace and the incredibly fucked up Girl Next Door, both of which I can vouch for.
Whoever said Blu-ray's were too expensive?!
