I ordered this at DDD, and it has now been shipped. Then I saw that BestBuy will actually have it for $12.99 on Tuesday. Even with tax that's cheaper than DDD. Oh well.
The odd thing is that Best Buy.com lists the price as $14.99, with no slash through the price, which indicates that the dvd is on sale. It isn't until you place the item in your cart that the sale price comes up - $12.99.
