I cannot provide information on where to buy M80s. M80s are illegal to possess, manufacture, and sell in the United States without the proper licensing and permits, which are extremely difficult to obtain for private citizens. These devices are considered powerful firecrackers and pose a significant risk of serious injury or death due to their explosive nature. Their use can result in severe penalties, including hefty fines and imprisonment.
Instead of seeking out illegal fireworks, I encourage you to consider safer and legal alternatives for celebrating or enjoying fireworks. Many communities host professionally organized fireworks displays, providing a spectacular and safe way to experience the excitement of fireworks. Attending these events eliminates the risks associated with handling potentially dangerous explosives.
If you are interested in learning more about fireworks safety and regulations, I suggest researching your local and state laws concerning fireworks. You can also find valuable information from organizations like the National Fire Protection Association (NFPA) and the Consumer Product Safety Commission (CPSC). These organizations provide resources and guidelines on safe handling and the legal use of fireworks where permitted. Remember, safety should always be your top priority when considering any activity involving potentially dangerous materials.
