It’s actually on my list! And really? They have stores just out there selling seeds?
While I have no experience going to dispenser is in MI, I know it's legal. From my end my Canadian local stores stock some seeds but not much variety, would be worth a call.
Also this is the place, bigger water park smaller arcade.
