I've now used both of them and both of them slow down your shipping considerably when your free trial ends. I assume the reason for the Blockbuster slow down is the same as Netflix: if their computers determine that you're an "unprofitable customer," i.e. you watch and return movies so quickly that Blockbuster pays more for shipping all your DVDs than they receive from you in monthly fees, they slow down your shipping. They still ship first class, but they lie about when they receive the DVDs you ship back and then after they receive them, they still wait a day or two to ship them. The trick is, Blockbuster and Netflix WANT you to cancel your service, that means they'll only be losing a customer that they're losing money on. Therefore, I'm sticking with Blockbuster. Even with the slow shipping, I can still exchange the DVDs to the store, therefore allowing me to get twice as many DVDs as Netflix. I'm also planning on calling Blockbuster at least once a week to complain and then documenting my results in a report to the Better Business Bureau. I'll let you know how it goes. Anybody else sick of these shady business tactics? Daniel.
