Alaska... Colorado.... So hard to tell apart.
PROBABLY they have a mail chimpanzee located in one office as an experiment to see if they can save a few dollars...
Mail gets handed to the mail chimp, and he decides what box it goes in. Sometimes he gets it right, sometimes your seeds go to alaska. This also explains the condition boxes sometimes arrive in.
Heard they are planning on rolling out the mail chimp (instead of the much more expensive small package bundle sorter) nationwide as part of obamacare next fall.
