amazon store fee is the cost associated with running an Amazon store, particularly if a seller is using the Fulfillment by Amazon (FBA) service. While setting up an Amazon Store itself does not incur a fee, there are other costs involved, including storage fees, fulfillment fees, and selling fees. Additionally, if a seller runs ads or promotions for their store, there may be associated costs. It is important for sellers to factor in these fees when budgeting for their Amazon business.
