At Best Buy, purchase two select movies on Blu-ray starting at $9.99 each and get a third movie of equal or lesser value for free. (Click the box beside "Add to Offer" on your choices, then click "Add to Cart"; discount shows in cart.) Opt for in-store pickup to avoid the $5.99 shipping fee. Choose from titles like Underworld, Zero Dark Thirty, Hotel Transylvania, 21 Jump Street, or Monty Python and the Holy Grail.
