Q: Can Sku Grid able to distinguish between Prime items sold by Amazon and sold by third-party sellers?
A: Yes, Sku Grid have the ability to exclude 3rd party merchant fulfilled offers. When adding items to the grid, you can add the tag #skuopt:lowestprimefba to the end of your URL or simply select Lowest Prime Offer Excluding 3rd Party. See screenshot: https://jmp.sh/ciJfhMn When Sku Grid checks the supplier, it will only use prime offers that are either shipped and sold by Amazon or Amazon FBA, and exclude those 3rd party merchant fulfilled items. If only 3rd party merchant fulfilled (even if they are prime) offers are available then the item would be considered out of stock. It will only be allowed as in stock if the item is available under amazon fulfillment and prime eligible.
