The great State of Michigan imposed a 6%safety fee on top of the 6% tax. They also made all the retailers carry $10 million in insurance. Only a few other states mandate insurance and they are $1-2M. Big Fireworks is based in Lansing and carries most items. They dont have anything that is spectacilar as most items are just relabled items base on other importers proven pieces. For a man that knows his shit on pyro head to Jackson to Sparkys fireworks paradise. http://fireworksparadise.com/
