Received them so far from SD, SF, LA. However, I'm a third-timer w/ the mcat. From speaking w/ these schools, the impression I got was that since my previous scores aren't stellar, they gave me the benefit of the doubt and sent me 2ndaries based on the strength of my overall app. This was definitely something new I learned in the process. Davis and Irvine, though, might be waiting for Aug scores. Drew seems behind the other programs.
So it appears that it's not necessarily a taboo to take the mcat 3 times. Applying early is a blessing, I have to admit. I thought my friends were crazy when they told me to apply the first week, but it's been great getting 2ndaries back early. Hope this helps, Wonderboy!
