Wow! Amazon has the Interstellar on Blu-Ray [1] for just $3.99 (down from $12.97)! This would make a great stocking stuffer.
Shipping is FREE with an Amazon Prime membership [2] (get a free trial here [3]) or get free Super Saver Shipping a purchase over $49.
Remember that Amazon prices can change very quickly, so I cannot guarantee how long this price will stick around. Make sure to double check the price before you purchase. Make sure to check out the Amazon deals [4] section on Bargain Blessings for more bargains!
