Private Supplier Dropshipping refers to a dropshipping arrangement where entrepreneurs work with private suppliers who are not listed on major platforms like AliExpress or Oberlo. This model allows for more control over product quality, pricing, and branding. By partnering with a private supplier, dropshippers can differentiate themselves from competitors and offer exclusive products that are not widely available. Private supplier dropshipping also offers the potential for higher profit margins since entrepreneurs can negotiate better deals and establish stronger relationships with their suppliers.
