This invention provides an information providing system which can easily update a price in accordance with data processing, an information providing apparatus, an information presenting method, a control program, and a storage medium. To accomplish this, a user accesses a Web server (121) in a photosite (105) by using a browser (120) of a user PC (102), browses images, and selects an image which he/she wants to print out (S2, S3). A printsite (109) receives input data indicating a print form, print count, and the like for each selected image (S6), calculates an estimated price by using a print information database (119) in which print unit prices are stored and the price calculation module (110), and transfers the estimated price to the photosite (105) (S7). The photosite (105) calculates a price while factoring personal information into the estimated price by using a personal information database (118) and a price calculation module (108), and presents the price to the user (S8).
