What are the best firework showrooms in Wyoming?

I'm planning to go up to Wyoming within the next couple of weeks to get some basic fireworks, like firecrackers and roman candles. I just want to know whats the best showroom that offers the best price. I was going to go to phantom, but they seem over priced, and I have a very minimum budget of 50-100 dollars. I want to get AS much stuff as possible, without blowing my money on a overpriced showroom does anyone know the best low priced showroom in Cheyenne? Last time I was up there was over 5 years ago.
