The system should check the availability of an item in [url removed, login to view] every one to twenty second, and add it to shopping cart and check out automatically . I should be able to set up price critera based on the selection I am watching, quantity of item added to cart, payment method, shipping method. The system should be able to use up to 20 [url removed, login to view] account at the same time.
