A process for optimal economic efficiency in postal operations generally comprises the steps of conveying objects from a first repository and pre-processing a combination from among at least one of said objects based on assigned criteria, such as variable pricing methods, to derive further value from these operations. The pre-processing collects recipient-specific optimized combinations of objects and stores them as deliberables in a storage system. Such pre-processing obviated the need for set ups required under the prior art thereby reducing operational costs, including the indirect costs of equipment "down time". Pre-processing further achieves the postal discounts offered by the U.S. Postal Service thereby eliminating the need for the additional pre-sorting systems required under the prior art. Moreover, variable pricing methods are employed to optimize the economic potential of these operations.
