great catch. hope you were able to use the extra 10% discount coupon. bought office space and napoleon dynamite 2-disc yesterday for $6.29 each after 10% discount (before tax). returned the a knight's tale unrated which i bought 2 weeks ago from bestbuy for $9.99. bought it again but together with starship troopers se and every time we say goodbye for $5.99 less 10% each.
Unfortunately, the 10% discount did not work at my Bestbuy. BUT! I was able to fool them by pricematching the 1disc 1976 Hills Have Eyes ($4.99) CircuitCity Sale with their 2disc 1976 Hills Have Eyes ($26.99).. a $22 savings.
And congrats too, maximizing your purchase! Yeah, I agree there are also some $5.99 scattered at BB which were not advertised.
