I reached out to one of a renowned brands in the US for a potential opening of a Wholeasale account. It provided us with a list of distributors instead. I informed the brand that I am an FBA Seller and I would require a LOA and support in case Amazon wants to know if I have authorize to resell your products.
Brand’s response: “We do not provide letters of authorization nor do we have the ability to support Amazon/3rd party platform sales. This will be between you and Amazon.”
There is nothing you can do unless you cozy up to someone internally at the brand. Unfortunately Amazon became a race to the bottom and renowned brands don’t want their price to drop or image tarnished.
