Three ways major companies sell on Amazon

There are 3 ways major companies sell on Amazon

FBA Fulfilled by Amazon - Using a seller central professional account they sell their own products and manage the listing

Vendor Express - Using a vendor central Amazon will issue a PO to purchase bulk orders of the product at a big discount and then they become the seller. In this case, Amazon manages the listing, the stock, and the fulfillment

Wholesale - By allowing third-party sellers to sell their products online using Retail Arbitrage or Wholesale. This is when you see 10, 20, or even 100 sellers on the same listing (it’s called fighting for the Buy Box)

The most common for major companies will be the second and third options.

By having Vendor central account they gain access to AMS Amazon Marketing Services!
