Curious, will such a move by Amazon make 3rd party sellers fear them more and move to other marketplaces like jet.com or ebay.com? Given amazon's margins really come from its marketplace, they might cannibalize that? Yes, amazon's value for 3rd party sellers is its massive distribution compared to others but its a supply/demand game. If 3rd party sellers start to move to other platforms, maybe jet/ebay can spend more to acquire more demand?
