You are ill informed and don't know where to shop.And just what are you smoking?
Standard DVDs still sell at $15+ at Target. The movies that went straight to video are $10.
I can't see the day when they drop that low. It wouldn't be worth it to manufacture, distribute, stock and put them on the shelves at that price.
Target is the worst place to buy DVDs. Their Target consumer is solidly middle class so the store charges higher prices than others.
Shop elsewhere and find low prices on DVDs. I pay at most $10 for a newly released, popular movie and only $5 or less for one that was released a while ago. Target charges double this amount.
