That&#x27;s because Walmart doesn&#x27;t offer third-party fulfillment (to my knowledge). They allow select third-parties onto the selling part of the platform (but again, not open like Amazon), but fulfillment remains the 3rd party&#x27;s problem to handle, which is why the shipping price is still an issue there.<p>Amazon is providing far more of the value chain than other e-commerce sites, and it&#x27;s no surprise to me that they&#x27;re charging for that. If that doesn&#x27;t work for a given seller, they shouldn&#x27;t use Amazon. If enough people don&#x27;t use Amazon, Amazon will have to adjust. I see no evidence that the latter is occurring in great numbers.
