They do not.
I have a case here and read of two more on GlockTalk just today. My GSSF RO contact confirms.
The guy here was able to get his sent to a contact in Tennessee, we are in North Alabama.
They told one that "We would have to get permits to sell them in Alabama." Another heard that it was the inconvenient way that Alabama taxes are set up. The first is BS, the second may be true, but it is strange that other vendors don't get discouraged.
