...I actually still get Netflix DVDs haha..but they've kinda gave up on throttle and now just go to several days no matter what at least that's been my experience the last 2 or so years.
Oh they'll mark it as returned quickly but now they give the expected arrival as several days later. It used to be a 3 day total for me for return,ship, and arrival (under most circumstances).
I sent my disc back on the 17th, they shipped a new one on the 18th, it said expected arrival as the 21st but I did get a nice surprise..it came today
