I've been a happy Netflix user for years now. I've only slightly looked into Blockbuster's and Wal Mart's online rental sites. It seems like Netflix has a much better selection than both. (I'm really into foreign and independent films.) My mom has been testing out the various sites. She told me that Blockbuster got her the DVD's much quicker. That it was because the USPS tells Blockbuster that a DVD is being returned, thus eliminating the wait time for it being sent back. For those of us two days from the delivery center, that means a lot. So I suggested to Netflix that they do the same. I'm writing this to get more Netflix customers to try the same thing. It will benifit us all. Go to: http://www.netflix.com/ContactUs - and click on Suggestions.
