Red Envelope Madness!
There's also one in Madison, Wisconsin according to my envelopes (faster shipping since last time I had a NF account, yay!).PO Box 7997Madison, WI 53707-7997
Thanks, Will! I've added it to the list.
I think I saw elsewhere that there is also a distribution center in Springfield, IL. I'm a Blockbuster Online customer thinking about switching to Netflix if this is true.
