amazon fba storage refers to the space provided by Amazon in its fulfillment centers where sellers’ products are stored before they are sold and shipped to customers. FBA storage fees are based on the volume of the product, with different rates for standard-size and oversized items. Sellers must also account for long-term storage fees, which apply to products that remain in Amazon’s warehouses for an extended period. Efficient inventory management and regular restocking can help minimize storage fees.
