It's a dance: To maximize your Netflix account, you know you have got to get that movie in the mail on Thursday, so it'll be processed on Friday and you can get a movie on Saturday. . . But if you ship that disc on Friday, you know that Netflix won't touch it on Saturday, and you'll have to wait for Monday processing. Some people don't even receive Saturday discs in their area!
Well, the seeds of change have been sown, my friends, because Netflix Saturday is coming up — confirming reports from back in January  that Netflix would take on Saturday processing, so not only would you be able to receive discs that day, but a disc sent on Friday that got there Saturday would be sent out in time for a Monday delivery (phew). Of course, that's banking on Netflix doing their speedy one-day processing.
In any case, members in East Coast and Midwest regions have begun seeing Saturday processing , which hopefully means it'll bleed into everywhere else soon.
Me, I'm watching all my inboxes until then.
