I love that they know their fireworks as well. They don't do deals like the others. They just price theirs lower than everyone else's. We always go to the one on 2300 in lehi. I have also heard good things about some dudes fireworks. I believe Both drive into Evanston with a large truck and some friends and buy a ton at discount. Sometimes going to Evanston is cheaper but unless you are buying 1-2 thousand dollars worth then you probably won't get a great discount there.
