Definitely Netflix.com. It is the best DVD rental service available todate. I have been using Netflix for over a year and extremely happy with it. They provide very fast delivery that no other service (I tried both Blockbuster and WalMart) can even come close.
I am poed with netflix over the 28 day wait after the release date, not all movies but probably more than 50% that i have on my list. That and the fact that if you start getting alot of discs they start screwing you. Been thinking about switching to blockbuster because i would not have to deal with the 28 day wait. Plus they are a little cheaper. But with there financial debt i not sure if they are going to stay afloat.
Hmmm... I thought the 28-day wait was just for BDs. Didn't realize it was for DVDs too.
Anyway, as someone who only rents some (mainly for BDs) to supplement my prefered choice to own, I prefer Blockbuster Online -- it's cheaper, especially for BD rentals, besides the lack of 28-day wait (and possibly better turnaround times for BDs?). I don't do the VOD/streaming thing though, which some NF customers like.
I'll deal w/ it if/when Blockbuster does go under...
