I am looking to purchase 6 pieces of your product and would appreciate a detailed quote. Please include the unit price, any applicable discounts for bulk orders, and specify the transport cost to 14700 Praha, Czechia. Additionally, if there are different shipping options available, I'd like to know the estimated delivery times for each. It would be helpful to understand your payment terms as well. Thanks for your assistance!
