At Best Buy, buy one select Blu-ray movie and get a second for free. Prices start at $7.99, with most at $9.99 and $14.99. With free shipping, most pairs of movies are at the lowest total price we could find by far. It's alsto the best "BOGO" offer we've seen from Best Buy. (Its last BOGO required you to buy two Blu-rays to get one free.) Sales tax is added where applicable.
