Pretty much my experience exactly. Both NF and BB ar located in Lansing, probably where yours are shipped from as well. The closest BB store to me is in Swatz Creek and I've only exchanged there once because it's about a half-hour each way. If you could just swap the disc you received by mail at the store and then mail back the one you picked up it would be nice but of course that's not the case. Guess I can't complain too much since I was given it for free and am a Platium sub anyway...........

Yep, Lansing is my distribution center. I wish Blockbuster by mail could have the same turnaround time as Netflix, but if you have a store that is convenient for you the exchanges make up for that.
