ABSTRACT:
Impulse purchasing is provided for packages of services offered to consumers via an information network. A plurality of services is offered for individual purchase on an impulse basis via a user terminal coupled to the information network. The plurality of services is offered for purchase as a package on terms that may be more favorable than when the services are purchased individually. Upon purchase of a package, a package record is established for access by the user terminal. The package record provides cryptographically secure access to services provided in the package during a defined time period over which the package is valid.
