Principal Insurance anyone?
Nancy,
There is a link in the menu on the left of your forum screen titled "Insurers" -- in there, you can find your insurance carrier (if anyone else has used them).
I went there to look for Principal and there are two.. principal financial and principal healthcare. I dont' know if they are the same... it seems to be split down the middle for the people who gave responses.. but again, I think it's really going to depend upon what your insurance policy covers.. if you don't have it in your coverage, it doesn't look like either of the principal groups will relent.
