Is there any violation against Amazon for having two accounts? What is best practice?
My personal account is on my personal email, my seller account can be under the business email address but since it will be a home-based business, my shipping address on my personal will be the business address of the professional.
There is no problem with this. Just make sure you don’t buy anything from yourself.
Please note that Amazon Sellers can have as many Buyer Accounts as well, as long as they are not used to manipulate product reviews, cast helpful votes on related seller’s products or to purchase from Amazon to resell on their site.
