If my product has 2 variations, can I create 3 different listings, like:
In 1 listing I am selling 2 variations of this product
In the 2nd listing, I am selling 1 of this variation and the same goes for the 3rd listing.
Does amazon allow me to do this? If yes, will it affect my inventory?
No that is against terms of service. Only 1 listing per product is allowed.
only 1 listing you can make
Yes, Amazon allows you to create separate listings for different variations of your product. also you can check this link for more information - https://sellercentral.amazon.in/seller-forums/discussions/t/965d6427-93be-4e6a-9407-8f3bfbd0e8af-Golang Tutorial
