“Overall, my experience at Cornellier Fireworks was nothing short of incredible. The selection, customer service, and overall atmosphere of the store were top-notch, and I would highly recommend it to anyone in need of fireworks for any occasion.”
“What really sets this place apart from everywhere else is the staff. I go here every year, and every year I have a lot of questions about everything. They are more than happy to explain what each firework does, and even help you navigate through the thousands of fireworks that they sell. They have everything...bottle rockets, mortars & everything in between. And it's buy one get one. Works for me!”
“WOW! So many fireworks! The by 1 get 1 free is what makes this place affordable.”
