amazoin seller is a misspelling, but it refers to the same thing as an Amazon seller—a person or business selling on Amazon’s platform. Becoming an Amazon seller involves creating an account on Amazon Seller Central, listing products, and managing sales. Sellers can choose between an individual plan for small-scale selling or a professional plan for larger volumes. Amazon provides tools like FBA (Fulfillment by Amazon) to help sellers handle logistics and customer service, making it an attractive option for entrepreneurs.
