I see your point....Perhaps with a more restrictive delivery environment, they might up the number of DVD’s one could have out at a time, to make up for it. Such as, instead of one DVD out at a time, they could make it two for 8.99/month. That way, a customer could mail back his DVD’s Mon through Wed, and get two new DVDs by Fri...Sound like a plan?
I find the 3 DVD plan to be optimal. Always got a movie to throw in at any given time, and I usually end up mailing back two at a time in the same envelope. And there is always a movie or two worth streaming at any given time.
