Does anyone know of a place online that you can buy diapers with Cash On Delivery, so that you can pay upfront with cash? And I think UPS says they have the C.O.D. shipping option but I don't know how to use it. Does anyone know how? So far my best bet is checking craigslist constantly, but craigslist never works because they usually won't come to your house, or you at least have to call them on phone usually.
