I must say that the quality of publications so far in regards to Starfinder is truly horrifying.
I received my first shipment of the core rulebook from Amazon last week, and upon taking it out of the very well-packaged box, I noticed that the spine was already damaged and separated from the Binding. Quite unacceptable for such a high dollar book. Sadly, Amazon has no copies to replace it with, but according to numerous accounts online, the quality of other rulebooks doesn't increase in the slightest.
Yesterday, I received the Alien Archive from Amazon. Now, at first glance everything seemed fine, but upon closer inspection, I noticed that ten or twelve pages were missing from the book. Thankfully Amazon is shipping a replacement, but to be honest I have very little confidence in it being complete upon arrival.
This equates to two pretty serious strikes, and unless something changes, I don't see myself continuing to purchase products from Paizo.
