Amazon is now having a Buy 2 Get 1 Free Blu-ray Sale, which is happening through December 17.

Add three illegible Blu-ray titles to your shopping cart, and get the lowest priced item for free. You have to add all the items to your shopping cart to see the discount.

Here are some picks from the list of 172 qualifying Blu-ray titles that I’d probably grab if I actually had a Blu-ray player …

Blade Runner (Five-Disc Complete Collector’s Edition) $27.95
National Lampoon’s Christmas Vacation $19.95
The Lost Boys $19.95
Harold & Kumar Go to White Castle (Extreme Unrated) $19.95
Superman II – The Richard Donner Cut $19.95
The Orphanage $24.95
Justice League: The New Frontier Special Edition $20.95

Check out the Blu-ray Sale page to see all the Blu-ray titles. Remember, the lowest priced item is free, so it’s probably best to get three titles that are around the same price.
