Interesting... I noticed a couple years ago that if I put the DVD in the return envelope backwards (and the bar code couldn't be seen thru the little window) it took longer to mark those movies as returned (I'd get the email at 3, 4, 5 PM instead of 7 or 8 AM) and it often led to an extra day of waiting. I now take care to always have them in the right.
You haven't noticed any extra delay by doubling them up?
