Recently, I had a large order including the revised Crimson setting. It was a very expensive order and also contained all my monthly materials. When it didn't arrive with several days of shipping, I contacted Paizo. They checked and said that the post office showed it 'In Transit,' and I would have to contact them to initiate a case to find the package.
I did so (hard to do since you can only do it during business hours - who does that any more in this day - only the Post office). They opened a case, and an agent called two days later. She basically said that the status was the status, denied they ever received the package, and said I had to contact the shipper.
I did so, and Paizo immediately sent out a replacement.
Now, I've had over 162 orders with Paizo, and this is the first time I can remember having a problem. In this case, since the post office showed it 'in transit,' to me that seems they implicitly acknowledged the package was in their system. I hope Paizo pursues this with those rascals because I don't see how this can be Paizo's fault.
Anyway, Paizo is the best!
