A system for injecting and ejecting virtual connected buttons on an operating system (OS) interface includes one or more communications channels connecting a host to on-line product/service acquisition sites, information on a user's purchases from the acquisition sites, a virtual purchasing connected button (VPCB) for each product/service the user buys from an acquisition site that can be displayed on an interface of the OS of the host, and an online-purchasing system manager that triggers, based on that information, a deferring action of the display of the VPCB on the OS interface for one or more products.
