If an order is received before noon, then the order is likely to be received the next day by the customer. If the order is received after noon, then the order is likely to be delivered to the customer the following day. If the order is placed on a Friday before noon, then the order will likely be shipped on Monday. If order is made Friday afternoon, then the order may not process until Monday, and, therefore, ship on Tuesday. Weekend orders (Saturday & Sunday) will not be delivered until Tuesday. Always exclude Saturday and Sunday in your calculations - orders (usually) will not deliver on Saturday or Sunday (so exclude them from the day count like they don't even exist). When an order is made on Saturday or Sunday, it does not process until Monday, and is expected to be delivered on Tuesday. As you can see, expressing shipping times precisely is complicated, especially when you have to account for different manufacturer shipping policies. That is why we just call it "RAPID DELIVERY" (calling it overnight can be misleading).
