Dear, Hello, because our products are mostly heavy cargo, we cannot deliver all products to your door by express delivery in all regions, remote areas, for example, Xinjiang, Tibet, Qinghai, Inner Mongolia, Yunnan and other places can only send logistics to their capital cities. If you want to transfer to your city, you need a certain amount of arbitariec. This arbitariec is paid when you pick up the goods, for specific products, specific regions, specific situations, and specific analysis, please consult our customer service for details. If you can only send logistics customers, we will contact you before shipment. Dumbbell error is 1-2kg, please contact Customer Service for specific questions.
