1. An online computer system that causes a certain numerical value displayed on a checkout webpage of a third-party retailer website to change in value, the online computer system comprising:
first software installed on a computing device, coupled to a network, the first software configured to cause storage of digital codes that cause the certain numerical value to change when applied to the checkout webpage of the third-party retailer web site;
a browser extension software installed on a user device of a user, with a display, that is operably connected to the network, said browser extension software configured to:
receive a plurality of digital codes over the network from the computing device;
responsive to a user access of the checkout webpage, generate a graphical user-selectable element to be presented on the display;
responsive to a user selection of the graphical user-selectable element, automatically perform following steps:
applying at least one of the plurality of digital codes to the checkout webpage to invoke a respective function on the checkout webpage without user entry of the at least one of the plurality of digital codes, thereby triggering the checkout webpage to receive the at least one of the plurality of digital codes and to return a respective response to the at least one of the plurality of digital codes; and
determining the respective returned response to the at least one of the plurality of digital codes from the checkout webpage to determine whether the at least one of the plurality of digital codes causes a change in the certain numerical value and determine a respective amount of change in the certain numerical value caused by the at least one of the plurality of digital codes; and

after the user selection of the graphical user-selectable element, apply the at least one of the plurality of digital codes if the respective amount of change in the certain numerical value caused by the at least one of the plurality of digital codes satisfies a criteria.
