I renewed December 22 and it didn't come and didn't come and didn't come. Finally, I called last week on Thursday or Friday and they looked up my account and said that I ordered the 2010 MRB with my renewal instead of the 2011 MRB. (Can't see how that is possible, I followed all instructions.) However, if I did make the mistake and order the 2010 MRB it's kinda funny because they didn't send me one!
so anyway, I received mine (2011) in the mail today -- a couple of business days after calling.
