I'm looking for a wide variety of colorful fireworks that create a big impact with their explosive effects and loud sounds. Ideally, I'm interested in options that cater to different occasions, and I'm curious about the range of colors and effects available in your product lineup. Could you please provide me with a detailed pricing list for these fireworks? Specifically, I want to know about bulk purchasing options and any discounts you might offer for larger orders. Additionally, information on packaging and shipping would be great, as I'm planning to make an order soon. Thanks!
