The same thing happened in Florida, since PAM is a poison it required a license in each state to be shipped into or sold in that state. Pro Products decided that it was costing them too much for all of these licenses so they didn't renew their licenses in the states that ordered the least.
it sucks... I have 2 options now, drive to Georgia where I can pick some up (a 8 hour round trip) or get someone I know who lives in another state to order some, then somehow get it to me.
