Interesting.
I haven't seen any of these posted by either of the MSCs I determined have been mentioned in this thread. However, after I signed in and searched the knee company, I suddenly got two e-mails from them.
Low and behold, the location near me (which should have shown up when I signed in and searched yesterday) is suddenly available. I just clicked the link in the e-mail that showed all the locations in my state.
I'd really like a sub, but I think I'll wait to see if they add a shop fee to it.
