The Computer Warehouse purchases its inventory from more than a dozen different vendors. Orders are placed via telephone, fax, or on the supplier$$s Web site. Most orders are delivered the next day. Most orders are filled completely in one shipment, but sometimes a supplier is out of stock of a particular item. In such situations, the bulk of the order is shipped immediately and the out$-$of$-$stock item is shipped separately as soon as it arrives $($such shipments of back orders are never combined with any new orders placed by the Computer Warehouse$).$ The Computer Warehouse pays for some of its purchases COD but usually pays by the $10$th of the month for all purchases made the prior month. None of its suppliers allows it to make installment payments
