Here you can read how to find the URL of the supplier's product feed file:
- Log in to your supplier's web page and search for this or for similar pages: Dropship, Wholesaler list, Data, Product Data, XML data, CSV data... etc.
- You can write the supplier an email and ask him this: "I want to sell your products in my online store. Do you have product feed file which is updating regularly? (CSV, XML, XLS, JSON or TXT file)"
