I'm looking to import a quantity of 25,000 puffs of Bang Vape and would like to inquire about the unit pricing for this order. I'm anticipating placing an order for around 500 to 1,000 pieces, depending on the pricing and available options. Could you please provide detailed information on the pricing structure, any bulk purchase discounts, and your lead times for delivery? Additionally, I'm interested in knowing more about the product specifications and available flavors or models. Your prompt response would be greatly appreciated, as it will help me make a timely decision. Thank you!
