Cornellier Fireworks

Cornellier Fireworks is a family-owned fireworks retailer with shops in Beloit, Poynette and Windsor, Wisconsin, and South Beloit, Illinois. The stores carry name brands such as Black Cat, Great Grizzly, Shogun and Megabanger, with everything from sparklers and firecrackers to artillery shell kits and 500-gram cakes. Firecrackers, bottle rockets, Roman candles and fountains are also stocked.

The showrooms stay open and stocked year-round rather than operating only as seasonal tents, and the busiest stretch is the run-up to July 4th, when the company suggests shopping in early to mid-June for the best selection. Buy 1 Get 1 Free deals run every day in store. Shoppers from the Chicago suburbs and Madison area both stop in, and the Beloit shop sits near the state line along I-90/94.
