A storage fee was a fee levied to pay for the use of an area as storage space. In 2372, upon being informed that the now-empty Quark's was to be used to store furniture from level two of Deep Space 9's habitat ring while repairs were being made, Quark pled with Benjamin Sisko to at least pay him a storage fee. Sisko told the Ferengi to send him the bill. (DS9: "Body Parts")
