Hello, I am sorry to hear you are unhappy with your purchase. When buying from Amazon you are purchasing directly from the wholesaler themselves so they are able to provide better pricing. We are located in Canada so the import costs and shipping needs to be added on the price as they are not as affordable as importing into the USA. The margin on this is very low for us. As for Shein, it is well known this brand has many human rights violations, so you'll see cheaper prices due to cheap labour costs in which they can potentially afford different fabrics. We buy our harnesses directly and ethically from a team of people who we pay fair wages to who make them by hand. We try to price everything as fairly as possible and we understand how the fast fashion industry has skewed peoples perspective of garment production.
