When Blockbuster started thier $20 a month unlimited rentals deal, I had a feeling it was a result of NetFlix's success. Looks my intuition was correct. You can now have Blockbuster deliver DVDs straight to your house for $20 a month.

By the way, this is a great deal. I've been doing the $20 a month plan there for about 6 months or so, and it rocks.
