All products sold by our factory are wholesale prices, and we only earn a little margin. Therefore, we do not offer free shipping for all products. Please understand and forgive us! However, we will contact the express and freight companies we have long-term cooperation with to give you a preferential price. The shipping fee for this series of products is calculated based on the weight of the product. Since the weight and specifications of each product are different, the shipping fee will also be different. Please contact the customer service after you purchase the product to calculate the accurate shipping fee, or consult the customer service to choose the appropriate logistics method according to the weight and volume of the goods you choose. Thank you!
