Abstract: Analysis has revealed that there is an undue proliferation of first-class mail being sent each month in the nature of bills, statements and similar such documents. Analysis has also revealed that this produces an unnecessary expense for postage and processing, besides the costs involved in purchasing the paper and envelopes to begin with.The method of the invention avoids this through the single mailing of one or more two-sided documents on which is presented all the bills, statements, etc. intended for a given recipient during a specified period of time, for all subscribers to the service.In accordance with the described embodiment of the invention, the method forms a computer database of addressee information; merges with that database all such record information provided by subscribers; prints out one or more sheets, preferably on both sides, of all information intended for designated recipients during the time period in question; and allows for a single mailing of such sheets in a single envelope.
